geWorkbench

Revision as of 13:14, 9 August 2007

Feature requests for geWorkbench

Feature requests not listed in Mantis

* list management: i.e. union, intersection, etc, visualization of sets: Venn diagrams should be possible to select from more than one data object or even between projects

there is a gray box displayed when starting the application

import projects to exsiting live projects

full support for cell files, chip chip data, all Affymetrix data type/formats ( cel files, cnt files, expression chp files, genotyping chp files (LOH Estimation and Genotyping Analysis), exp files, experimental result summary) chemical information (SD files), ODBC connections

3D visualization of PCA projections

genomics visualization tools: ploting features on genomic regions with zooming functionality

visualization of multiple chips at the same time

Vector graphics in publication quality

more annotation features for graphics (Title, comments, regression lines, etc)

better linking of table cells to selected data (highlight OR display selected data within all data)

being able to deal with sequences as input for numerical calculations: what is needed here are different ways to encode nucleic and amino acids. There are different matrices that can be applied but also self adapting algorithms one of which I developed during my PhD thesis...

different kinds of artifical neurral networks.

the application should be much more memory efficient

various kinds of visualization should be included/improved. 3D visualizations, box plot, ...

annotations should be visible somewhere. there should be a display that shows all/selected types of annotation/additional information about a marker or Array.

=> All information that is read into the program should be visible through some interface.

In the open file menu, remote access one has to right-click to get vital information about the data being retrieved. It is very unintuitive to hide essential information in a right-click.

it should be possible to clean the temp folder from within Workbench to be able to revert to the initial installation configuration

It should be possible to do a pairwise/multiple sequence alignment from within sequence retriever or for a set of sequences to see differences in sequences that come up for the same marker. Selecting all sequences for a specific marker, adding them to a new sequence object and then doing a sequence alignment would be ok, too.

search function in Help is missing

General Features

0000700: progress bar for saving/loading (not only the workspace)

Mantis: 0000482: "All Markers" and "All Arrays" overrides are confusing

In order to successfully uses the marker and phenotype panels, the user must create selection sets, enable those, optionally set them as case/control and ensure that "All Markers" or "All Arrays" is not checked in their component. This seems very difficult for a user to learn, and is not a very intuitive approach. There must be a better way to manage selections.

It might be sufficient to describe the basic concepts of geWorkbench (like this one) in the documentation AND tutorial etc...

Mantis 0000410/494: Rewrite Visual Builder.

What is the status of the "Visual Builder"????

Mantis 0000401: Panel selection/deselection impropely affects visualization components

As it turns out (per Andrea) this behavior is an artifact of the relative color scheme (does not appear for the absolute color scheme). I think we will need to change this in the future: one would expect activated panels to have an impact on the contents of a visual component only if the visual component has indicated that it wants to take into account activated panels.

somebody should go through all components and check that they all respond correctly to all events they should respond to. Quite a few bugs relate to events not being handled correctly. E.g.330 where the sequence panel does not clear when a project is being removed.

Bugs related to system state problems: 0000612, 789, 794

Mantis (242): Unable to save more than one panel

This relates to actions (save, delete) on multiple selections in Project Folder and Marker and Arrays/Phenotypes panels, where only the first the selected is being used

Mantis 0000480: Workflow support

Would be nice to have true workflow support for regular users (without the need for scripting).

(agreed: Bernd)

Mantis 0000740: selections in Project folder

When selecting the Workspace, or Project from another object the views that relate to that latter object are still available. It is impossible to know what is being calculated.

When leaving an object the display should be reset to an empty state

Not in Mantis:

There are problems related to memory management. geWorkbench uses too much memory for storing Microarray data internally. When loading 9 U133 chips one needs more than 512MB.

Mantis 0000114: Persisting configuration settings designated through the visual builder

At present, changes to the start up configuration effected during the application execution (through the Visual Builder) do not get persisted: when the application is launched the original start up configuration is used again.

It is desirable that changes introduced by the Visual Builder be persisted in the application's configuration file so that they can be "remembered" at the next launch.

Mantis 0000115: Choosing among available application "flavors"

During application launch, a start up window (which the user can opt to hide for subsequent application invocations) should prompt the user to select one among the available application configuration "flavors". This functionality should be available not only at start up but also from within the application, through a "Preferences" type of menu option.

Mantis 0000077: Context sensitive online help

We need to make online help available in a context sensitive manner: from within a component, a user should be able (using F1 or by pressing a Help button) get access to the online help associated with the component.

Mantis 0000156: Extension of event exchange model
Entering this here as a placeholder regarding the proposed re-engineering of the event model. Some of the design suggestions that have been mentioned include:
- Making it a rule that event data are always interfaces.
- Removing the need to specify within the throwEvent() method the listener interface and the method to invoke in that interface.
- Using annotations (or some other mechanism) in order to provide a direct reference to a service provider so that methods can be invoked directly rather than through event exchanges.

Mantis 0000157: Extend framework to bring to focus components that receive appropriate events

An issue with the GUI is that one needs to know which components respond to which events in order to inspect the results of some action. E.g., when executing the hierarchical clustering analysis and in order to review the results one needs to explicitly select the Dendrogram tab.

The framework needs to be extended so that components can gain the focus as appropriate when they receive certain events.

Mantis 0000173: UI Tab Display.

Tabs should be displayed in alphabetical order. It's difficult to find tabs as they are ordered currently.

If the user cannot view all the tabs without scrolling, the tab headers should become drop down values.

Mantis 0000478: File save/load operations are memoryless in terms of last directory used.
There are many places in the app where data are being loaded from or saved to disc. When such an operation is used for the *second* time the app should remember the directory the user navigated to the *first* time. Some specific examples where this is not the case:
- Exporting an image node from within the projects folders.
- Saving a data node from within the projects folders.
- Saving a panel from the Markers component.

Mantis 0000635: columns can be moved (applies to all tables)

when moving a column (which is not neccessarly bad) to the first position (row names) the row name is exchanged with a value but has this "button" look....

Mantis 0000547: Inaccurate Error Message

When connecting to a MAGE-OM Server the error message is "can not connect to server" even when it does connect and authenicate the user.

I changed the related code to reflect the real error.

But right now I have no available caArray RMI server to test this bug, if John can give me access to his local caArray server, I can confirm the bug is fixed or need more work.

Mantis 0000552: remembering parameters for different sequences

I have loaded two sequences. The visual pane remembers which of (Promoter, Sequence, Position Histogram) panes is used for each sequence. But it doesn’t remember the individual options within those panes for each sequence. E.g. when I select the line view for one sequence and the Full sequence for the other, it will display the last selected viewing option.

There should be some consistency here: Either you remember everything or nothing for different sequences.

Mantis 0000693: end of memory

Is it possible to warn the user if there is no more memory? Especially on the MAC we are using for testing(where one has to wait quite some time sometimes) I would find it helpfull to know that geWorkbench crashed and is not waiting or doing something....

=> It seems there is nothing we can do about it, but if a child process dies due to memory problems we should be able to identify this and let the user know.

Mantis 0000620: results are not associated with a dataset

Programmatic features

Mantis 0000400: Inconsistent t-test results based on phenotype/panel activation order

There should have been no significant genes found once the marker selection had been made but the volcano plot was erroneously displaying the genes that had been selected as being significant. This is due to an inconsistency in the way the markers() method is implemented in CSMicroarraySetView. For the time being I've routed around this method but it should probably be changed at some point.

Mantis: 0000509: Error when trying to create network from saved workspace

0000794: Component state is not saved for any component

The problem is caused by the differences in type and semantics between workspace folder and project folders. For example, The "File" submenu offers "Open" and the pop-up choices are "File" or "Workspace". Select Workspace and you are offered a dialog box. Select "File" and you are told you must first select a project node. Or if you select "New" (an adjective) from the submenu, you get a choice of "Workspace" or "Project". Select "Workspace" and the current workspace folder is cleared of its contents. Thus New Workspace actually REMOVES the Workspace folder, whereas the submenu item "Remove" does not include "workspace" as an option. Select "Project" and a new project folder is added without replacing an existing one. I think the whole thing could be made more obvious and logical by making the File submenu items "Workspace" and "Projects" and perhaps "Files". Then the choices under each could be actions (verbs) - e.g Open, Remove, Load, Delete, Save, etc. In other words, you consider the folder that you want to do something to, select it in the file menu and choose the action that you want to take. Also the other file items "Export" etc. have nothing to do with the Project Folders Area and are positioned awkwardly.

File

Mantis 666: merging data sets in project folder doesn't work

Mantis 0000578: marker names are incorrect
Mantis 0000790: Implement a check on chip type selection

File loader should be rewritten; Exp files should be read in twice to verify file format and probably assign Affy chips automatically

Mantis 0000345: File Loading Confusion

No choice to list all files in directory. The file selection box should contain an option to see all the files in a directory, otherwise unclear which file postfix goes with which loading option.

Mantis 0000347: Prompt to Save

No prompt to save workspace when application exits, there should also be a way to exit the application from the file menu.

Mantis 0000452: filtered datasets misrecognized on read in

If a dataset is filtered, written out, and then read in again, the "magic marker" that defined the chip type may be deleted, and the dataset can be recognized as another entirely. For example, my HG_U95 dataset, after filtering out half the markers, was recognized as HG_133_Plus2.

Mantis 0000479: Enable the "Export" functionality for data nodes.

This functionality is supposed to be similar to the "Open file" functionality, where a number of pluggable export filters can be used to export a dataset into another format. At the vry least we should support exporting microarray data into the Cluster (http://rana.lbl.gov/EisenSoftware.htm) [^] format.

Mantis 0000484: At the File menu, an "Exit" menu item should be provided.

Many many other softwares do have it. Maybe an option for saving the workspace should be provided before exit.

Mantis 0000465: Support loading Affymetrix .CEL and .CHP formatted files

geWorkbench 1.0/caWorkbench v3.0 are capable of reading in only the .txt version of Affy files. Many users (including Northwestern) have indicated it would be tremendously beneficial to support .CEL, .CHP files as well. The former contain probe level data, rather than the probeset level data which the workbench is currently designed to handle. As such, loading of .CEL data will probably have to be coupled with the immediate execution of a normalizer capable of translating probe level data to probeset level data.

=> CEL is already working

Mantis 0000418: Chip type selection dialog appears with dataset switch

If the application doesn't recognize the chip type of a dataset it will ask you to select it, but it will keep asking you every time you switch to the dataset even once after you've picked that type once.

Mantis 0000549: GUI Poorly Formatted

The GUI for connecting to a remote ca-array server is poorly laid out - Port and Protocol should be on the same line, URL should have its own line, there should be larger room for User Name and Password.

Mantis 0000742: directory not remembered

when reading in an annotation file (through the "other" option) the directory of the last load is not remembered.

Edit

View

Commands

Panels

Panels should be called sets

Tools

Visual builder

Preferences

Mantis: 0000513: Changing visualization in preferences has no immediate effect

Help

Mantis 0000466: Add "shortcuts" screen

Add a "shortcuts" screen (maybe under the "Help" main menu item?) to list available shortcuts like the very useful F12.

Mantis 0000548: No documentation pointer to MAGE-OM Setup

Although there is documentation in 1.03 geWorkBench describing how to connect to a MAGE-OM server, it is not detailed, does not describe the protocols and has no pointer to the MAGE-OM documentation.

Mantis 0000511: Help topics not alphabetical

The main help topics in the online help are not in alphabetical order.

Project Folders

Mantis 0000730: feature request: union / intersection

being able to combine e.g. fasta sequence/merge data sets

Mantis 0000604: select menu-file-open-workspace

=> new workspace is not confirming deletion of old one

Mantis 0000739: right click image nodes should show option to export

if there is an image in the project panel there should be an additional option to export the image. Now one has to go through the File menu.

Mantis 0000633: copy function

Since all the operations are destroying the original data I believe it could be useful to have a copy function that copies a state of a data set to a new data set.

Mantis 0000643: ask if should really remove

I think it is good practice to ask the user if he really wants to remove an object. Accidents happen and if you put a lot of work into one it is rather disappointing if you accidentally remove your work... (This is only ment for projects and dataset, not for images or such)

Mantis 0000543/571: removing more than one project/data set only removes the first one

Mantis 0000571: sequence selections under Project folder

1. load two or more sequences in different project files.

2. by holding the ctlr key select more than one sequence.

=> two sequences are selected, but you cannot do anything the both together. How do you combine different sequence into on project such that you can select from the combined sequences?

Markers

Arrays/Phenotypes

Mantis 0000393: Inconsistent GUI element

there is no save/load functionality for arrays as there is for sets

Mantis 0000415: Panel Label is not prepopulated with last entry.

I performed the following step: - Loaded webmatrix.exp - Added 3 arrays to the selection panel - Selected an array> Add to Panel and typed over the "Section' and entered Panel A - Then another array > Add to Panel. The Panel label text box was no longer prepopulated.

Expected Result: The Panel label should be prepopulated with the last label created (Panel A).

Sets

Mantis 0000381: Renaming a label erases its class (case, control, etc.) status.

Renaming a label erases its class (case, control, etc.) status. To reproduce, set a label's class to 'case', then rename that label.

Mantis 0000451: if filter after clustering, dendrograms become invalid

1. Load a dataset and perform a hierarchical clustering. 2. View in the dendrogram panel. 3. Now filter out some values so that the size of the dataset is decreased. 4. run hierarchical clustering again. 5. View in the dendrogram panel. Now select the first cluster output in the project panel. 6. Because the reduced dataset does not match the orignial cluster, the drawing fails with numerous bad consequences across the interface

How to handle changes in dataset size is a design consideration that must be worked out, for example by 1. duplicating the orignal dataset so that dependent datasets remain valid, or 2. remove the dependent datasets that have become invalid. User should be prompted before such filtering on a dataset that has dependent datasets.

FASTA sequences

Promoter Panel

Mantis 0000712: Promoter Panel Logo Tab needs a header

It would be good to change the color of the currently selected TF. Now it is just a little bit darker blue. Try Black or red/ light red.

Mantis 0000653: position of promoter panel

To me the promoter panel is more an analysis module and should be in the lower right area (analysis area) rather than in the viewing area (upper right).

Mantis 0000593: manually adjustable p-value changes automatically, which should not happen, any user changable variable should NOT be overwritten

Mantis 0000655: after scan displayed panel is changed

The active/displayed view of the promoter panel is changed to Sequence-Line view whenever a scan is performed.

Especially when changing parameters it can be really annoying.

Mantis 0000660: selection is not used for pattern discovery

=> It is a known issue and need further discussion.

Mantis 0000697: progress bar color doesn't change to red if process is interuped under MAC

Sequence Panel

Mantis: 0000330: Sequence panel does not clear when project removed.

Mantis 0000575: edited sequence causes problems

load attached document
open sequence view
edit sequence (right click on sequence in Project folder, view in editor)
remove 7 nucleotide (AATAATT) around position 380 (the line should now be 70 nucleotides long as all the others)
activate the sequence (line view) in the sequence panel such that the sequence is shown below the line view
click on the arrow bars

=> sequence disappears.

Also the sequence from the modified filed is not the one show. The original sequence is shown.

Matnis 0000748/651: sequence line should show postion/window of displayed sequence

It would be benificial to have a small window/box or indicator that shows the position of the displayed sequence within the multiple/single line view.

(see also sequence retriever)

Mantis 0000650: holding down arrow for moving sequence

it would be nice to be able to scroll through the sequence not by single clicking on the arrows but also by holding the arrow down. then the squence should slowly be moving

Position Histogram

Mantis 0000792: Filter function

The Filter button does not seem to do anything. I also don't see any effect from the Avg./Peak button. Also, the online help states that the flex. threshold is not implemented. If these are not in use they should probably be removed or at least deactivated.

The filter button is in fact connected to a pretty sizeable method called computeAllPatternStatistics() which has the following note attached:

// Assuming a binomial model, the average density should be given by the likelyhood * SeqNo * size of step

// and the variance should be sqrt of that. For the time being, we assume a uniform likelihood

And eventually seems to update each pattern's pvalue.

Mantis 0000732: display is not updated when parameters are changed

The way the component works now is correct but maybe not very intuitive. We should at least re-examine how it works in comparison with the other graphical tools and try to harmonize if possible.

Bernd suggests just coloring the plot button red if an action is pending but not yet executed (awaiting the plot button being pressed). Another alternative would be to change the plot button to a checkbox called "Active" or something like that.

Is the plot button needed for performance reasons? Why is it actually there?

Simulation

Mantis 0000608: why can a simulation be performed on an image?

Simulation can be used for any object, why? Can it be at least moved to the beginning? So it is not the panel that pops up all the time first?

Network Generator

Phenotype & Optimizer Options

Interactions Display

5. Sequence alignment

Mantis 0000544: fastacmd support doesn't exist

I don't know if there's a plan to implement fastacmd in geworkbench, but if there is, would I find it in sequence alignment? What options will be available? => Don't know why we would support this??

BLAST

Mantis 0000787: subsequence blast is not working

build in some functionality to copy part of a sequence to a new sequence, or even better to be really able to edit a sequence, and create a new sequence.

Mantis 0000751: up/down keys not working

This problem is seen when navigating in the target sequence area (left panel) of the results panel for BLAST. Even though the selection is moving in the result view on the left hand side (the blue selection is moving) when using the up/down keys the corresponding alignments are not shown. This only works when using the mouse

Mantis 0000734: naming conventions for alignment results and imported sequences

Blast results get their name from the first name listed in the actual blast output. The db field is set to the appropiate database. When importing a sequence using "Add selected sequence to project" a random number is used for generating an artificial name for that sequence. The name of the sequence is derived from the NCBI (gi name). There is no additional information in the data history history on where the sequence comes from.

Needed functionality:

- Dataset history should reflect where the sequence is coming from: i.e. which blast run, wich result entry

- the name of the sequence shouldn't be a random number but rather the name of the first sequence that is imported. In case there are multiple sequences with the same name a number should be appended separated from the original name by and underscore.

- The name of the sequence should be same as the one from the alignment result.

Right now it is impossible to trace back where a specific sequence is coming from.

related to 0000541: blastall is not complete

using local / own databases

Mantis 0000521: Need dates for BLAST databases

People need to know the creation date of the BLAST databases they are running a query on. They cannot just trust that we have the latest. It would be great if a query could be done to import this info into geWorkbench, if not, then there should be a link or button that would bring up the appropriate web page on the AMDeC website. Really it should be in the interface though.

Mantis 0000671: load in alignment result is not working (as I expect)

I would just remove the load button. Why would you want to do this in the first place? I would understand if this button would be on the analysis component of Blast but in the result component... ????

HMM

Pattern discovery

Mantis 0000496: sequence masking needed

A major planned workflow of geWorkbench is to be able to search for patterns in sequences surrounding co-regulated genes. However, no provision is made to mask or deal with masked sequences. Many patterns found in unmasked genomic sequence can be expected to be in repeated elements of various types (or does Splash already have a way of dealing with this?). Solving this may involve enhancements to both the Pattern Discovery module and perhaps to the Splash server. The Splash server currently is believed to recognize mask characters N and #.

Searching for regulatory patterns is potentially very sensitive to the details of how it is carried out, as such patterns may be short and embedded in regions of repeated sequence. The greatest possible degree of flexibility and control may be required.

Suggestions:

We will assume we can obtain from the Sequence Retriever sequence that is either unmasked or is reversibly masked, that is with small letters denoting masked seqeunce and capitals denoting unmasked.

The following options could be considered:

If lower-case-masked sequence is available, provide the option to convert masked characters to Ns before sending to the Splash server.
We could host a repeatmasker server (www.repeatmasker.org). We could then mask sequence as desired, e.g. mask low complexity but leave in LINE elements. There are many considerations and subtleties discussed at repeatmasker.org.
The Splash server itself could be enhanced to offer simple masking, along the same lines as the BLAST programs do.
We should give some indication of the kinds of statistics one could expect from true conserved patterns vs those arising from repeats. Can they be distinguished?

Mantis 0000665: conceptional inconsistency

Pattern discovery is the only component I came across so far that has “Pattern discovery” (itself) in the analysis section. All other modules just have “Experiment Info”, etc. and in the visualization area the results. Actually I do like the idea of having “itself” still in the analysis section because this way the parameters are still stored. But it is still inconsistent.

Mantis 0000648: navigation keys don't work properly

There are only two ways of selecting pattern such that they are displayed in the sequence window: Single click on a pattern and holding the shift/Ctrl key and using the mouse. There are other ways to change the selection within the pattern panel that have no influence on the sequence panel. Some of them are: using arrow keys, selecting more than entry with the mouse.

Mantis 0000627: selecting arrays and markers

It would be nice if markers and arrays could be selected/highlighted by double clicking on row / column headers

Drosophila and all other genomes are missing...

Mantis 0000748: sequence line should show postion/window of displayed sequence

related to (closed) Mantis 0000225: Microarray panel details

It would be nice to have the values (min, max) displayed next to the color legend

Mantis 0000326: absolute visualization needs viewing controls

If a set of unnormalized Affy data is read in, for example the cardiogenomics dataset, with the tools->preferences->visualization mode set to absolute, the dynamic range of the data is so large that only a few data points appear. Some options to deal with this would be:

1. a control labeled "Display as log transform"

2. an intensity control such as in the color mosaic panel.

Mantis 0000431: Table View does not sort properly

Sorting by most columns not work properly (does not order numerically or alphabetically) and attempting to sort by pValue appears to do nothing.

=> also true for any table

Mantis 0000550: color scale disappears when window small

If the window size is made small enough, the expression color scale disappears, leaving behind just its label. This may be common if people have small screens.

Mantis 600: The function of show marker is not clear. I might be useful to consider the following features/functionalities:

1. marker positions should be remembered when scrolling through plates. Either only for the plate that they were selected on, but probably even better for all the plates

2. Negative values should be marked in red, otherwise it is not possible to see the marker for a negative value

3. It would be nice if there were a correlation between the markers in the microarray viewer and selected markers from the Markers panel. Right now the Marker panel updates to the marker that is double clicked on.

4. When switching between "All Markers on and off" in the off-mode the marker selection is not shown, but when switching back to on they are shown. This should be somehow more consistent and the markers should also be visualized in the off mode

Gene Ontology

Mantis 0000623: Organization of panel is misleading

The Gene Ontology Panel is divided into three sub-panels: TreeView, TableView, P-value Trend. TreeView holds vital information for TableView and P-value: Chip set used, Reference List, selection to choose which of the above, and which class of GO terms is used. Those options/parameters should be visible in all of the three main panels since they heavily rely on them and should be moved outside of the panel structure within the GO panel!

affy ids are used for mapping to the GO tree structures. But then the gene names are use to do the calculations. Biggest problem here are affy ids with "---" as a gene name, they are all being folded into one set.

Mantis: 0000617: loading reference list

When loading an external reference list, basically any file can be loaded. Manjuanth told me that only affy id's are actually being processed. We need a way to show the user what actually was understood from the file that was just read. Something like the number of lines read, the number of identified affy id's, the number of non idenfied objects. Each of the non identified object should be displayed on the console. The help file should clearly state what the reference list file should look like.

Mantis 0000618: weird behavior - displaying reference lists

problem with large white blocks in markers area of component

GSEA

Reverser Engineering

Everything is going to be switched to the new version of cytoscape, then a lot of the issues will be resolved

By default cytoscape comes with two panels that can be selected (You will see them after resizing.) They cannot be switched by clicking on the panel heads but only by clicking on the panel names. (The other one was called sim1...)

Mantis 0000795: scatter plot not working

it is not plotted when the "All arrays" is not activated. If activated it is ploted. (but only the motif location plot)

one has to select mircoarrays in the Phenotype panel, but it is not enough to just select them, there has to be at least one named selection for the microarrays to be drawn.

one problem is related to GeneProfiler.java line 1140. Here it is evaluated if the panel size > 1 ((dataSetView.getItemPanel().panels().size() > 1)). I believe this is incorrect and doesn't account for selected markers that are not named...

Mantis 0000774: Motif Location Histogram does not default to all arrays display

The Motif Location Hisotgram display within the Reverse Engineering component does not follow the expected default display rule, whereby if no arrays are activated, then all arrays are considered activated. It only displays results if arrays are activated or the "All Arrays" checkbox is checked. It should really display all results if nothing is activated.

Mantis 0000799: results are not sorted by absolute value

The results in the reverse engineering panel are sorted by their numerical value. A negative 100 (-100) is displayed last whereas 100 is first. Since it is the absolute value that is interesting they should be ordered acordingly.

Mantis 0000802: Conditional analysis

load web4.exp from https://sharepoint.cu-genome.org/c2b2/Testing/head/microarrays/Reverse%20Engineering/data [^]
select first gene from markers list
analyze 2d
select conditional analysis panel
use 31350_at as gene1
gene2 should be 31314_at
select intersection
hit compute

=> last panel shows three times the same entry

=> the entry seems to be wrong

=> first panel shows all entries in duplicate with the same MI

Mantis 0000803: wrong name for gene1 gives exception in conditional analysis

user should be notified if the selection is not valid

Mantis user should be notified if the selection is not valid

prints too much, exports wrong things

Mantis 366, 472, 797: Mutual information/p-value distribution appears to be non-operational

Plot is not being drawn. This appears to be quite difficult and Manju is supposed to take care of this.

Mantis 0000678: Cytoscape - right click within graphics area

right click with the graphics area give you a lot of options including to search Google. Why not search NCBI, Pubmed?

Mantis 0000679: Cytoscape - resizing nodes

nodes can be resized within cytoscape and the size/shape is retained even when changing the model. There are two ways of getting the original shape back: 1. changing it manually, or 2. by switching to a different Adjacency Matrix and back. This is a bit awkward and inconsistent.

Mantis 0000677: conceptual inconsistencies

Reverse engineering is located in the visualization area and not in the analysis area. To conceptionally consistent the visualization and parameter selection should be separated.

Mantis 0000675: Cytoscape - Project Folders

When running multiple analysis creating multiple networks new item in the project folder are created. At the same time new entries in Cytoscape are created. This is redundant and confusing. There can (should) only be one, and it should probably be the Project folder one with all its drawbacks, just because it is more consistent. But do we then need the left panel showing all the networks?

Mantis 0000674: Cytoscape

Cytoscape comes with a whole set of menues and functionality that is not visible at first, only after resizing the window they come up.

=> this should be changed

Mantis 0000414: Layout problems

The layout for the reverse engineering component does not properly distribute space amongst the components. Upon first viewing the plugin one of the graphs is compressed to only 10-20 pixels high.

Mantis 469: documentation incomplete

Scatter Plot

Mantis 0000606: settings of properties are reversed when double clicking on marker

the tear-breaker!

Mantis 0000807: reference lines breaks at (1000,1000)

caBIO pathways

Mantis 0000583: Pathway Results not obvious

When a pathway is retrieved, a naive user does not know to look in the caBIO Pathways tab to find the results. User should be notified somehow

Marker Annotations and Pathway components should probably be combined, since they are inextricably linked.

Mantis 0000584: SVG Pathway Export

It would be great to allow easy export of the caBIO Pathway graphics. This is a great thing to give to a researcher, it looks very impressive. Failing that, a link where one could get the pathway would be nice.

Marker Annotations

Mantis 0000585: Export of spreadsheet data

Mantis 0000805: additional annotations requested
Mantis 0000806: new component for sequence and microarray integration

Andrea has suggested adding the option of retrieving from additional sources of annotation, including Entrez, GeneCards (Weizmann), etc. For a list see mantis report

a new data-agnostic component is needed for integrating data from sequence analyses and microarray data.

See additional info

Color Mosaic

Mantis 0000477: Missing right click actions

CM should have the right click actions consistent with Expression Profiles, EVD,Scatter Plot which supports zoom in/out,save as & print.

=> least have a mouse-over function that displays the chip and value for the spot

Mantis 0000611: color slider function not obvious (probably not only in color mosaic)

The real values displayed in a heat plot have to be mapped into a color space that is usually in the range between 0 to 1. A threshold has to be defined beyond which all values are mapped to 1 in the color space. By moving the threshold lower differences in the lower magnitudes can be visualized. This does not seem to happen in geWorkbench. I would expect to everything lighting up when I move the slider to one of the extremes. This does not happen.

Since I have seen the behaviour also in the other heat map representation and this is not the obvious behaviour it either has to be clearly documented what is happening or changed to "normal" behaviour

Mantis 0000642: information about arrays is missing

Let's follow here the exact same solution used in the Dendrogram component: there is a little sticky button with a bulb icon at the bottom right corner of the Dendrogram GUI. When pressed, moving the mouse over any spot reveals the array name, marker name and the expression value for the marker.

Expression Profiles

Mantis 0000524,471: no mouse over on expression graph (assigned to John)

Some of the components support displaying the marker name when a data point is moused-over. The Expression Profiles component does not, instead you must click on a line and view its name in the Markers panel. Mouse over would be a good enhancement.

Mantis 0000682: image snapshot is missing

Expression Value Distribution

Mantis (214): Double clicking on an activated array plot line does not make the array the base array

Mantis 0000572: domain and range axis: naming of axis confusing

Mantis 0000681: bounderies for selection are not all visible

This issue already was brought up few times. It is related to the package we used for drawing chart, JFreeChart. It is not very easy to extend JFreeChart to implement the two boundaries.

Analysis

The following analysis functions are requested:

Mantis 481: K-means is requested

mantis 0000307: Analysis should write to dataset history

When any type of analysis is done, basic facts should be written to the Dataset History log, such as whether all markers were used or an activated panel; the number of markers/arrays in the activated panel, and the array type, and a timestamp.

Fast Hierarchical clustering

Mantis 0000148: Euclidean distance shoud use normalized vectors

Data should be transiently normalized

Mantis: 0000485/000046: Aborting Hierarchical clustering does not really abort.

Mantis 0000594: Clustering on array dimension persists after used

Open a microarray dataset and run hierarchical clustering with the dimension selected as "both". After it completes, set the clustering dimension to "marker" and re-run the clustering algorithm. You will see that the dendorgram is still clustered in both dimensions. What you want here is for the dendorgram to be ordered in the original order of the arrays in the data file.

Matrix reduce

SVM classifier

Mantis 474: online help missing

Slmr classifier

SOM

Mantis 0000685: image snapshot only captures one cluster

It would be nice to capture as well all clusters at once.

Mantis 0000574: clarity for parameter description

I would like to suggest naming parameters with more contents. For example the parameter Alpha could be called learning rate (alpha), rows could be named Number of rows, Radius is only used for the Bubble neighborhood,

T-test

Mantis 0000516: Volcano Plot doesn't know data already log2 normalized

When a t-test has been done in the Analysis component, the results are displayed in the Volcano Plot (note that this component does not have an entry in Mantis yet). The display is on a log2 scale on the X-axis. However, the component does not know if the data has already been log2 transformed. I think it is essentially doing a second log2 transform of the data - that is, instead of just subtracting one log2 value from the other, it is taking the difference and then the log2 of this. Or it is taking a log2 transform of all the data again and then subtracting. Either way, it is displaying a log2(log2 X) value.

The only way to deal with this, is to know that the data has been log2 transformed. It would appear that this fact would have to be remembered if done in the normalizer component, or the user should be able to check a box on read-in that indicates the data is log transformed.

We can probably autodetect the log transformed state just on the range of values present in the input file.

=> auto detection is good, but we need to be able to set it manually, too. (BJ)

Mantis 0000637: stop button is missing for T-test

Mantis 0000638: t-test alpha corrections

I suggest to name the tab "corrections methods" and then divide them into "alpha corrections for t-distribution" and "Stepdown Westphal and Young Methods for permutation". Also there should be an error message when an option combination is selected that does not make sense (e.g. minP for t-distribution).

Multi T-test

Mantis 0000640: multi t-test message is missing message if there are too few data

Mantis 0000729: multi t-test and t-test don't get the same results

There is a difference between the results arrived from a single t-test and a multi t-test. With the current implementation it is not possible to get the same results with similar starting points

Resolution: change in MultiTTestAnalysis.java: tTest.tTest to tTest.homoscedasticTTest those results will be the same as when doing the comparable t-test with equal group variance, t-distribution, and just alpha correction.

Does it make sense to do a homoscedastic t-test, though? It seems that we should not assume that the between-groups variances are the same.

I would suggest to give the user a choice and document the different options.

Dataset History

Mantis: 0000300: need array info

We should be able to display information about a microarray - the chip type, the number of markers in the dataset vs in the chip definition.

Mantis 0000476: Data set annotation missing

Issue: Users analyze data, use activated sets, limit arrays included and none of these steps are captured in the annotation. The system should capture these steps for the user in a log so the researcher is clear on what the results include and how to reproduce.
