==Brief overview of changes in geWorkbench release 2.6.0==
 +
 
 +
 
 +
===Summary===
 +
'''geWorkbench 2.6.0.3''' was released on December 21st, 2016 as a minor but very important update.  It allows the BLAST and Sequence Retriever components to work again.
 +
 
 +
'''geWorkbench 2.6.0.2''' was released on February 20th, 2015 as a minor update.
 +
 
 +
'''geWorkbench 2.6.0.1''' was released on January 28th, 2015 as a minor update.
 +
 
 +
'''geWorkbench 2.6.0''' was released on January 22nd, 2015.
 +
 
 +
geWorkbench 2.6.0 was a major release, including more than 70 bug
 +
fixes and other improvements to usability.  All users should immediately
 +
upgrade.  Previous versions are no longer supported.
 +
 
 +
Please see the [[Media:GeWorkbench_v2.6.0.3_ReleaseNotes.txt | geWorkbench v2.6.0.3 Release Notes]] or [[Media:GeWorkbench_v2.6.0.3_ChangeLog.txt | geWorkbench v2.6.0.3 Change Log]] for full details of all changes.
 +
 
 +
===Java 7===
 +
With release 2.6.0, geWorkbench requires the Java 7 Runtime Environment (JRE).  Versions of geWorkbench including the 64-bit Java 7 JRE are provided for Windows, Mac and Linux. Use of the 64-bit JRE allows larger datasets to be loaded (through setting larger Java max heap sizes, described further below).
 +
 
 +
 
 +
===Installation Directory===
 +
geWorkbench no longer writes any files to its own installation directory; all files are now written to temp areas in the user's directory space.  This allows geWorkbench to be installed in normal System directories, e.g. "Program Files" on Windows and the Applications folder on Mac OS X.
 +
 
 +
===Larger Java Heap Memory for larger datasets===
 +
The default maximum Java heap size is now 2 GB for the 64-bit JRE7 installations.  Using the 64-bit JRE and larger Java heap sizes allows geWorkbench to work with much larger datasets.
 +
 
 +
On machines with larger amounts of RAM, users can now easily start
 +
geWorkbench with even higher amounts of Java Heap memory simply by clicking
 +
on specific command files available in the geWorkbench installation
 +
root directory (currently for Windows and Mac OS X only).  These files allow
 +
geWorkbench to be started with 1, 2, 4, 8 or 16 GB specified as the maximum
 +
size of the Java heap memory.  The user should
 +
take care not to request more heap memory than there is physical RAM memory
 +
available, and also to allow at least 1-2 GB for the operating system.
 +
All heap sizes larger than 1 GB require use of a 64-bit JRE.
 +
 
 +
The Windows launcher files end in .bat, while those for Mac OS X end in
 +
.command, e.g. "launch_geworkbench_winpc_4G.bat" and
 +
"launch_geworkbench_macosx_4G.command".  On either platform, the user can
 +
create shortcuts to the launcher files and place the shortcuts e.g. on the
 +
Desktop.
 +
 
 +
===BLAST===
 +
The BLAST component now complies with a new specification from NCBI for BLAST job submissions. BLAST submissions may not work in previous releases of geWorkbench.
 +
 
 +
===R===
 +
Several problems are fixed in how R is used from geWorkbench.  The R package directory setting in the geWorkbench Preferences component is now fully implemented and overrides any setting of the environment variable R_LIBS_USER.  This allows geWorkbench, if desired, to use a separate version of a package from those installed in regular R directories (e.g. geWorkbench downloads a special version of Viper).
 +
 
 +
===GenomeSpace===
 +
Integration with GenomeSpace is greatly improved.  GenomeSpace allows geWorkbench to exchange data with a number of other tools.
 +
 
 +
===CART===
 +
Access to the GenePattern 3.0 Classification and Regression Tree (CART) component is now included.
 +
 
 +
==Brief overview of changes in geWorkbench release 2.5.1==
 +
geWorkbench 2.5.1 was released on 11/01/2013.
 +
 
 +
geWorkbench 2.5.1 is a maintenance release.  However, it includes several important bug fixes and all users should update to this release.  Changes include:
 +
 
 +
* '''ARACNe''' - Exception on cancel fixed.

 +
==Brief overview of changes in geWorkbench release 2.5.0==
 +
geWorkbench 2.5.0 was released on 10/11/2013.
 +
 
 +
The geWorkbench tutorials will be updated in the coming days to reflect the major changes.
 +
 
 +
See also the [[Media:ReleaseNotes_2.5.0.txt| Release Notes]] for an expanded list of changes.
 +
 
 +
geWorkbench 2.5.0 is a major release.  Changes include:
 +
 
 +
* '''Workspace''' - The Workspace has been simplified by the removal of the "Project" level of data organization.  Files and data nodes are now loaded directly into the Workspace.
 +
 
 +
[[Image:Workspace_Open_Files.png]]
 +
 
 +
 
 +
[[Image:Workspace_data_node.png]]
 +
 
 +
 
 +
* '''Marker Annotations''' - The Marker Annotations component was completely reimplemented to use the bioDBNet data service rather than the discontinued caBIO service. 
 +
 
 +
* [[BLAST|BLAST]] - New parsing and display code was written so that all NCBI BLAST sequence alignments are now generated in geWorkbench from the BLAST results XML output file. This removes the dependency on specifics of the BLAST server HTML output.
 +
 
 +
* '''New Components'''
 +
** [[Consensus_Clustering | Consensus Clustering (GenePattern 3.0)]] - This component implements an interface to Consensus Clustering on a GenePattern 3.0 server.  Consensus Clustering uses multiple clustering runs to find consensus clusters and assess their stability.
 +
** [[LINCS_Query | LINCS Query and Display]] - The LINCS Query component provides for query and display of computational and experimental results from the Columbia LINCS center, which performs high-throughput drug candidate prediction and screening.
 +
** '''VIPER''' - VIPER summarizes drug activity on gene expression profiles at the level of the transcription factors. 
 +
** '''DeMAND''' - DeMAND is used to compute drug mechanism of action.
 +
** [[ceRNA_Query | ceRNA/Hermes Query]] - The ceRNA component provides query access to a database of precomputed competitive endogenous RNA (miRNA-mRNA) interactions for four different cancer types.  These interactions are computed using the Hermes algorithm.
 +
 
 +
* '''MARINa/MRA''' - The MARINa component has been separated from the MRA-FET version of Master Regulator Analysis. The "bar-code" graph first implemented in the MRA-FET Results Viewer component has now been adapted and added to the MARINa Results Viewer. 
 +
 
 +
* '''Online Help''' - The "Online Help" feature has been removed.  This material was identical to the geWorkbench tutorials, which are available at the geWorkbench.org website.
 +
 
 +
* '''Analysis Components''' - The "All Markers / All Arrays" checkboxes, which could be used to override marker or array set selections in the Markers/Arrays component, have been removed.
 +
 
 +
* '''ARACNe''' - The adjacency matrix, if saved to disk, is now written in the same format as used by the stand-alone version of ARACNe.  Each line starts with a hub gene, followed by all of its targets. 
 +
 
 +
* '''Skybase''' - Implement saving of image of histogram, and export of results to CSV file.
 +
 
 +
==Brief overview of changes in geWorkbench release 2.4.1==
 +
Version 2.4.1 is a bug fix release to deal with a few specific issues:
 +
* '''BLAST''' - Due to changes in the HTML output format of BLAST result pages from NCBI, results from an NCBI BLAST search could no longer be parsed into geWorkbench.  geWorkbench will now rely primarily on NCBI's XML result format, which should remain more stable.
 +
* '''ANOVA''' - A problem with activated marker sets has been corrected.  Incorrect markers may have been used.
 +
* '''Installation''' - The installer will now install geWorkbench to the user's home directory on all platforms.
 +
 
 +
geWorkbench 2.4.1 is only intended for use with Java 6.  A few incompatibilities with Java 7 are known to exist.

Brief overview of changes in geWorkbench release 2.6.0

Summary

geWorkbench 2.6.0.3 was released on December 21st, 2016 as a minor but very important update. It allows the BLAST and Sequence Retriever components to work again.

geWorkbench 2.6.0.2 was released on February 20th, 2015 as a minor update.

geWorkbench 2.6.0.1 was released on January 28th, 2015 as a minor update.

geWorkbench 2.6.0 was released on January 22nd, 2015.

geWorkbench 2.6.0 was a major release, including more than 70 bug fixes and other improvements to usability. All users should immediately upgrade. Previous versions are no longer supported.

Please see the geWorkbench v2.6.0.3 Release Notes or geWorkbench v2.6.0.3 Change Log for full details of all changes.

Java 7

With release 2.6.0, geWorkbench requires the Java 7 Runtime Environment (JRE). Versions of geWorkbench including the 64-bit Java 7 JRE are provided for Windows, Mac and Linux. Use of the 64-bit JRE allows larger datasets to be loaded (through setting larger Java max heap sizes, described further below).


Installation Directory

geWorkbench no longer writes any files to its own installation directory; all files are now written to temp areas in the user's directory space. This allows geWorkbench to be installed in normal System directories, e.g. "Program Files" on Windows and the Applications folder on Mac OS X.

Larger Java Heap Memory for larger datasets

The default maximum Java heap size is now 2 GB for the 64-bit JRE7 installations. Using the 64-bit JRE and larger Java heap sizes allows geWorkbench to work with much larger datasets.

On machines with larger amounts of RAM, users can now easily start geWorkbench with even higher amounts of Java Heap memory simply by clicking on specific command files available in the geWorkbench installation root directory (currently for Windows and Mac OS X only). These files allow geWorkbench to be started with 1, 2, 4, 8 or 16 GB specified as the maximum size of the Java heap memory. The user should take care not to request more heap memory than there is physical RAM memory available, and also to allow at least 1-2 GB for the operating system. All heap sizes larger than 1 GB require use of a 64-bit JRE.

The Windows launcher files end in .bat, while those for Mac OS X end in .command, e.g. "launch_geworkbench_winpc_4G.bat" and "launch_geworkbench_macosx_4G.command". On either platform, the user can create shortcuts to the launcher files and place the shortcuts e.g. on the Desktop.

BLAST

The BLAST component now complies with a new specification from NCBI for BLAST job submissions. BLAST submissions may not work in previous releases of geWorkbench.

R

Several problems are fixed in how R is used from geWorkbench. The R package directory setting in the geWorkbench Preferences component is now fully implemented and overrides any setting of the environment variable R_LIBS_USER. This allows geWorkbench, if desired, to use a separate version of a package from those installed in regular R directories (e.g. geWorkbench downloads a special version of Viper).

GenomeSpace

Integration with GenomeSpace is greatly improved. GenomeSpace allows geWorkbench to exchange data with a number of other tools.

CART

Access to the GenePattern 3.0 Classification and Regression Tree (CART) component is now included.

Brief overview of changes in geWorkbench release 2.5.1

geWorkbench 2.5.1 was released on 11/01/2013.

geWorkbench 2.5.1 is a maintenance release. However, it includes several important bug fixes and all users should update to this release. Changes include:

Brief overview of changes in geWorkbench release 2.4.0

Release Date: July 23, 2012

  • Significance Analysis of Microarrays (SAM) - An interface to an R implementation of SAM has been added. The user can choose an instance of R running on his or her own desktop, or access a remote grid service version with proper authorization.
  • Master Regulator Analysis - Major updates have been made to the MRA component.
    • The FET-based method now has the option of performing two FET runs on orthogonal slices of the data to determine the regulatory mode of the candidate master regulators.
    • The graphical result display has been completely updated. It now can display multiple bar graphs for multiple master regulator candidates, and uses a rank based ordering of the bars rather than the t-statistic value.
  • SkyBase - Adds access to the much larger PDB-60 database of homology model structures. As of 7/19/2012, the databases have:
    • PDB60: 12,264 structures, 7,804,258 models.
    • NESG: 946 structures, 1,943,390 models.
  • Affymetrix Human Gene ST whole-transcript and Human Exon ST annotation files - support has been added for Affymtrix Whole-Transcript Gene and Exon Array transcript-level annotation files. Examples include the Gene and Exon 1.0 ST arrays, and the new Gene 2.0 ST array. All whole-transcript Exon and Gene ST arrays use this format.
  • caArray - The interface to caArray can now query the newly released caArray version 2.5. However, it is not backward compatible with caArray 2.4 or earlier.
  • t-test - The t-test is now calculated using the Apache Commons Math Library. P-values may show slight changes due to improved precision.


Some, but not all, known incompatibilities with Java 7 have been corrected. geWorkbench 2.4.0 is only intended for use with Java 6.

Brief overview of changes in geWorkbench release 2.3.0

Release Date: March 16, 2012

geWorkbench v2.3.0 introduces significant improvements in responsiveness and memory usage, and a streamlining of the graphical interface to make using analysis, filtering, normalization and visualization components much easier.

  • The analysis, filtering and visualization components are now reached through a right-click menu directly on the data node, or through the commands menu in the upper menu bar. This allowed the removal of the dedicated "commands" area from the geWorkbench graphical interface, making more room available for the display of results.
  • Switching back and forth between large data nodes is now much faster.
  • caArray downloads have been speeded up dramatically, and memory problems that limited the number of arrays that could be downloaded were resolved. We have test-downloaded 527 arrays of type Affymetrix HT_HG-U133A in 16 minutes with no memory problems.
  • Dynamic search for marker and gene names has been added to all filtering components.
  • A number of data and result export options have been added. Microarray data can now be exported to a tab-delimited file directly, or from the tabular viewer, allowing subsets of the data to be exported.
  • Interactomes stored in the Cellular Network Knowledge Base can now be exported directly into the Project Folders component.
  • A new component, IDEA (Interactome Dysregualtion Enrichment Analysis), is included.

Brief overview of changes in geWorkbench release 2.2.2

Release Date: 8/19/2011

  • In the caArray download dialog, arrays are now sorted by name.
  • The following problems in using the Gene Ontology components were fixed:
    • Marker sets returned from the Tree Browser was not properly appearing in marker selection pulldown menus (e.g. ARACNe hub marker selection).
    • After restoring a saved workspace, the reference gene list in the GO analysis component was not populated.
    • In some cases, the GO Tree Browser returned markers having no EntrezID along with the expected markers.

geWorkbench 2.2.2 can be downloaded from the NCI GForge site at https://gforge.nci.nih.gov/frs/?group_id=78. Installation instructions can be found on the Download and Installation page of this Wiki. The Release Notes are also available on GForge.

Brief overview of changes in geWorkbench release 2.2.1

Release Date: 7/29/2011

This release augments the recently released version 2.2.0, and includes more than 90 additional enhancements and bug fixes, with many focused on network import, display and export, sequence retrieval, and pattern discovery. It also corrects two omissions from release 2.2.0.

  • Alternate file viewer for large networks that may be too large to view in Cytoscape.
  • Improvements to display of probeset-level networks.
  • Networks can now be imported either from ARACNe adjacency matrix files or from SIF files. Networks can be represented by gene symbols, Entrez IDs, probeset names, or other identifiers.
  • Adds support for use of alternate ontology files (e.g. from the GO website) for gene ontology analysis.
  • Sequence retrieval for DNA sequences is now based on refSeq records from the UCSC refGene table, and is available for all organisms with genomes supported by UCSC.
  • The new "Fold Change" analysis component, omitted from release 2.2.0, is included.
  • A feature to overlay a t-test result onto a Cytoscape network, not functional as released in version 2.2.0, now works correctly.
  • Bonferroni correction added to the ARACNe GUI.

Brief overview of changes in geWorkbench release 2.2.0

geWorkbench 2.2.0 is a major release containing more than 180 new features, enhancements and bug fixes. The most important of each are summarize below.

Overview of new features

  • New network comparison and manipulation features were added to the Cytoscape component,allowing comparison of CNKB interactomes to other expression datasets, projection of t-test results onto a network, and creation of subnetworks from the result of these comparisons.
  • The Gene Ontology component can now serve as a full, standalone GO term browser.
  • Options for import and export of interaction networks (interactomes) were added.
  • Two new filters were added to give the user options to deal with many-to-many relationships between genes and markers (probesets).
  • Two new analysis components were added. One calculates differential expression fold-change, and the second provides a front-end to GenePattern GSEA (Gene Set Enrichment Analysis).
  • Improvements were made to the Master Regulator Analysis component - it can now accept any user-supplied list of "signature genes", and the "bar-code" display was altered to match the style used in recent publications.
  • A new Social Center feature was added to the genSpace component, allowing users to directly interact with each other. Improvements in workflow

saving and visualization were also made.

  • A major code refactoring was completed, simplifying a number of core data structures to improve performance and prepare for the development of a new web version.

New features in detail

  • CNKB
    • (#2389) Export complete CNKB interactomes (SIF or ADJ formats). The Cellular Network Knowledge Base (CNKB) stores a number of "interactomes" derived from computational analysis of various types of gene expression data. These interactomes, and other interaction datasets, can be queried in geWorkbench to find targets which interact with genes of interest. With this release, complete interaction networks stored in the CNKB can be exported to a file, in either SIF format or as an ARACNe-format adjacency matrix.
  • Cytoscape
    • (#2424) Compare differential expression results to an interaction network ("interactome"). This feature calculates the Pearson's correlation coefficient for the expression profiles of each pair of nodes connected by an edge in an interaction network. Only those portions of the network which have a correlation coefficient above a user-set threshold will be displayed.
    • (#2424) Create a new subnetwork containing only edges exceeding the calculated correlation threshold.
    • (#2429) From an existing network, create a subnetwork containing only nodes in a marker set defined in the Markers component.
  • File Parsers
    • (#2388) Import an ARACNe adjacency matrix from a file. Either gene symbols or probeset names can be used.
  • Filters
    • Multiple probeset per gene filter (#2444) - For genes with multiple probesets (markers), retain only the probeset with: (a) highest coefficient of variation, (b) highest mean, or (c) highest median expression across all arrays.
    • Multiple Entrez GeneID Filter (#2445) - Filter out markers which are annotated to (a) no Entrez gene id, or (b) multiple Entrez gene ids.
  • Fold-change Analysis
    • (#2431) This is a new component that performs fold-change analysis and places markers that pass the specified threshold into two new sets in the Markers component, one for markers with positive fold-change, and the other for those with negative fold-change.
  • Gene Ontology
    • The Gene Ontology component is now always available when a microarray dataset has been loaded along with its annotation file. The GO Tree can be browsed or searched for any term. The markers annotated to any term can be returned to a new set in the Markers component.
    • (#1875) The most recent Gene Ontology OBO file is now downloaded automatically from the internet when geWorkbench is started, with the option to instead load a specified OBO file from disk.
  • GenePattern GSEA
    • A front-end to GSEA running on any GenePattern server has been added.
  • genSpace
    • A new social networking feature, the Social Center, has been implemented, allowing users to directly interact with friends or create networks (chat and share).
    • Users can now create their own Workflow Repository, where they can collect and comment on their favorite workflows.
    • The GUIs for Workflow Visualization, Real Time Workflow Suggestion and Workflow Statistics have been updated.
  • Master Regulator Analyis (#2523 and others)
    • Allow any user-supplied list of markers to be used for the phenotype signature.
    • Bar-code graph revised to match style of published work.
