About the MAT Knowledge Center
The Molecular Analysis Tools (MAT) Knowledge Center provides a centralized, authoritative repository of knowledge, information, and web-based support to facilitate the deployment and ongoing development of tools, standards, and infrastructure in the MAT domain. The Knowledge Center provides a platform for fostering open source development of MAT tools.

Tools Supported by the MAT KC
The following software tools are currently supported by the Molecular Analysis Tools Knowledge Center. Links are provided to the tool summary page for each tool, which provides an overview of the tool with links to resources including the knowledge base, forum, bug tracker, feature request system, and the developer's code repository.
caArray is an open-source microarray data management system which is accessible both via the web and programmatically. caArray guides the annotation and exchange of array data using a federated model of local installations whose results are shareable across the cancer Biomedical Informatics Grid (caBIG®). Visit the caArray page for more information.
caIntegrator is a web-based software application that allows researchers to set up custom, caBIG®-compatible web portals to conduct integrative research, without requiring programming experience. These portals bring together heterogeneous clinical, microarray and medical imaging data to enrich multidisciplinary research. Visit the caIntegrator page for more information.
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 50 available plug-ins supporting the visualization and analysis of gene expression and sequence data. Visit the geWorkbench page for more information.
GenePattern combines a powerful scientific workflow platform with more than 150 computational and visualization tools for the analysis of genomic data.
Tool Adoption Case Studies
Many academic institutes and research/commercial organizations have adopted various caBIG tools in the past. In this section we link to a few key documents where caBIG tool adopters have created materials about their experience for the benefit of those considering an adoption project of their own.
Refer to Tool Adoption Case Studies.
Integration of Tools
There is extensive integration among caArray, caIntegrator2, caIntegrator, geWorkbench, and GenePattern. For example, geWorkbench and caIntegrator2 can retrieve microarray data directly from caArray hosted at NCI or on a local server. GenePattern is also connected to caArray for data retrieval. caIntegrator2 and caIntegrator use GenePattern as one of its data analysis services.
Instead of developing all data analysis modules independently, geWorkbench and GenePattern each can invoke several modules of the other party to provide a comprehensive data analysis platform. To learn how to use these tools together, please check out corresponding tool's wiki pages as well as the forums (End Users forum and Developers forum) dedicated to the integration of these tools.
Visit MAT Knowledge Center Forum
The Molecular Analysis Tools Domain Forum. is for visitors to submit questions and comments that are beyond the scope of any specific tool, but that are within the domain addressed by the Knowledge Center. What questions or comments do you have that extend beyond the coverage of the existing tool set? Write your thoughts in this forum.
