Tool Overview
caArray is an open-source, web and programmatically accessible array data management system. 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®). caArray furthers translational cancer research through acquisition, dissemination and aggregation of semantically interoperable array data to support subsequent analysis by tools and services on and off the Grid. As array technology advances and matures, caArray will extend its logical library of assay management.

Integration with other tools
Integration with geWorkbench
geWorkbench can query for data in an instance of caArray via a Java API. Several operations are supported. You can:
- Query for experiments, for example by platform or by species.
- Select from which hybridizations in an experiment you wish to download data.
- Download derived (summarized, probeset-level) data that has been parsed into the database. An example is the values loaded from Affymetrix CHP files (created through GCOS/MAS5). geWorkbench does not currently support retrieving or analyzing Affy CEL files directly.
The current release of geWorkbench, version 2.1.0, connects with caArray 2.3.0, 2.3.1, and 2.4.0.2
For more information, visit the geWorkbench project page.
The software can be downloaded.
Integration with caIntegrator
caIntegrator can extract the genomic data from caArray hosted on either a private server or the NCI site. You can:
- Extract the genomic data into caIntegrator.
- Integrate the genomic data with the clinical data and imaging data in caIntegrator.
- Perform genomic data analysis with the built-in GenePattern Tool within caIntegrator.
The current release of caIntegrator, version 1.2.0, can work with caArray 2.3.0, 2.3.1, and 2.4.0.2 .
You may use the publicly accessible NCI site. To install a local copy, download a copy of software.
Integration with GenePattern
GenePattern has a module that can retrieve data from caArray using its Java API. The caArray2.3.0 Importer lets you retrieve raw data files from caArray by experiment name or id. You can specify the extension of the data file that you want to download. The default is .CEL.
You can process CEL files using the GenePattern module ExpressionFileCreator. Once you have used ExpressionFileCreator, the data can be further analyzed using many different GenePattern analysis modules.
The caArray 2.3.0 Importer module is compatible with caArray v2.3.x. You may download the caArray2.3.0Importer.
The caArray 2.1.0 Importer module is compatible with caArray v2.1.x and v2.2.0. You may download the caArray2.1.0Importer.
You may also download GenePattern.
Once you've fetched your microarray data from caArray from any of the above versions of the caArrayImporter, you can use that data in any GenePattern module or pipeline that accepts gene expression data. To view compatible modules from within GenePattern you can click the context arrow next to the imported file (the result file of your caArrayImporter job in Recent Jobs) to see which modules can accept this dataset.
