Notice on updating of geWorkbench tutorials for release 2.4.0
geWorkbench 2.4.0 will be released on July 23rd, 2012. All tutorials affected by changes in 2.4.0 have been updated ahead of the release. Therefore, you may see features mentioned which are not present in release 2.3.0.
Brief Overview of Major Changes in Upcoming geWorkbench Release 2.4.0
Projected 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 1.0 ST whole-transcript and Human Exon 1.0 ST annotation files - support has been added for these Affymtrix annotation files.
- 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.

Current Release
Welcome to geWorkbench. The current version is 2.3.0, released March 16th, 2012.
View the geWorkbench 2.3.0 Release Notes.
geWorkbench 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.
Overview
geWorkbench (genomics Workbench) is a Java-based open-source platform for integrated genomics. Using a component architecture it allows individually developed plug-ins to be configured into complex bioinformatic applications. At present there are more than 70 available plug-ins supporting the visualization and analysis of gene expression and sequence data. Example use cases include:
- loading data from local or remote data sources.
- visualizing gene expression, molecular interaction networks, protein sequence and protein structure data in a variety of ways.
- providing access to client- and server-side computational analysis tools such as t-test analysis, hierarchical clustering, self organizing maps, regulatory neworks reconstruction, BLAST searches, pattern/motif discovery, etc.
- validating computational hypothesis through the integration of gene and pathway annotation information from curated sources as well as through Gene Ontology enrichment analysis.
geWorkbench is the Bioinformatics platform of MAGNet, the National Center for the Multi-scale Analysis of Genomic and Cellular Networks (one of the 7 National Centers for Biomedial Computing funded through the NIH Roadmap). Additionally, geWorkbench is supported by caBIG®, NCI's cancer Biomedical Informatics Grid initiative.
End-user and developer support for geWorkbench is provided through the caBIG® Molecular Analysis Tools Knowledge Center, a component of the caBIG® Enterprise Support Network.
Graphical User Interface
The figure above shows the full geWorkbench graphical user interface. The Cellular Network Knowledge Base B-cell interactome was queried for interactions of two master regulator genes, and the result displayed in Cytoscape.
