Plugins are sets of pluggable components for geWorkbench.

Below is the list of available plugins.

Microarray Visualization

Plugin Description Compatibility
Color Mosaic Displays heat maps for microarray expression data, organized by phenotypic or gene groupings. Verified to work on 3.0
Dendrogram A tree-structured diagrams reflecting the results of hierarchical clustering analysis. TBD
Dot Matrix Displays the syteny analysis results as a comparison of two genomic regions with detailed annotation for both regions[[.<A - I'm not sure if I should move this to Sequence Analysis]]> tbd
Expression Profiles Expression of genes across several arrays/ hybridizations. TBD
Expression Value Distribution A distribution plot of the expression values for one or more microarrays. TBD
Marker Annotations Supports the retrieval of CGAP annotations for genes within a marker panel. TBD
Microarray Panel Color-coded levels of gene expression using a color scale varying gradually from red (up-regulated) through black (no change) to green (down-regulated). TBD
Scatter Plot --. TBD
SOM Clusters --. TBD
Tabular Microarray Panel The numerical values of the expression measurements are displayed in a table format; each row represents an individual probe and the columns display the signal and background intensities and intensity ratios.

TBD

Data Management

Plugin Description Compatibility

Normalizers

Plugin Description Compatibility
Array-based centering Subtracts the mean (median) measurement of a microarray from every measurement in that microarray. TBD
Marker-based centering Subtracts the mean (median) measurement of a marker profile from every measurement in the profile. TBD
Mean-variance normalizer For every marker profile, the mean measurement of the entire profile is subtracted from each measurement in the profile and the resulting value is divided by the standard deviation. TBD
Missing value calculation Replaces every missing value with either the mean value of that marker across all microarrays or with the mean measurement of all markers in the microarray where the missing value is observed. TBD
Threshold Normalizer All data points whose value is less than (or greater than) a user-specified minimum (maximum) value are raised (reduced) to that minimum (maximum) value. TBD
Quantile ?. TBD
Housekeeping The system is able to normalize data based on the values of user selected house-keeping genes. TBD

Annotation

Plugin Description Compatibility
Dataset History This non-editable component records data transformations induced by data-modifying operations. ?
Dataset Annotation A text box used to annotate data files, projects and images. ?
Experiment Information This non-editable component allows for viewing experiment information associated with a Microarray dataset. ?
Image Annotation Captures comments ?
Marker Annotation Retrieves CGAP annotations for selected genes. ?
CaBIO Pathway Listing Displays BioCarta pathway diagrams for selected genes. TBD-- ?

Analysis

Plugin Description Compatibility
Hierarchical Clustering Hierarchical clustering groups markers into clusters on the basis of similarities in their expression profiles to form a hierarchical tree that can be viewed in the Dendrogram View window. ?
Self Organizing Map (SOM) Displays heat maps for microarray expression data, organized by phenotypic or gene groupings. ?
T Test -- ?

Filters

Plugin Description Compatibility
Affy detection call (Affymetrix data only) Sets all measurements whose detection status is any user-defined combination of A, P or M as missing. TBD
Deviation Sets all markers whose measurements deviate below a given value across all microarrays as missing. ?
Expression threshold Sets all markers whose measurements are inside (or outside) a user-defined range as missing. ?
Genepix Flag Filter --. ?
Missing values Discards all markers that have “missing” measurements in a user-defined range of microarrays. Another filter must first be applied however, in order to generate the missing values upon which this filter can operate. TBD
2-channel threshold (Genepix data only) Defines applicable ranges for each channel, and sets all values for which either channel intensity is inside (or outside) the defined range as missing. TBD
