The NCI instance of the caArray database is now retired. For details about the retirement, see the caArray Retirement Announcement. |

caArray is an open-source, web and programmatically accessible microarray data management system that supports the annotation of microarray data using MAGE-TAB and web-based forms. Data and annotations may be kept private to the owner, shared with user-defined collaboration groups, or made public. |
While caArray is a web-based application, it does have a dependent software stack, which includes: MySQL 5.0.27 database; JBoss 5.1. (hosts the caArray grid service and the caArray application); and JEMS installer 1.0.2 GA (supports EJB 3.0 specification)
Dependent Software | Version | URL |
---|---|---|
J2SE Development Kit | 6.0 (J2SE 6.0) | |
Apache Ant | 1.7.0 | |
MySQL | 5.1 | |
JBoss for UPT | 5.1 | – |
JBOSS for Grid Service | 5.1. | – |
JBOSS for caArray application | 5.1. | – |
You can contact the NCI CBIIT Application Support if you have any questions or concerns.

geWorkbench can query for data in an instance of caArray via a Java API. Several operations are supported. You can:
The current release of geWorkbench, version 2.5.0, connects with caArray 2.5.0 and 2.5.1
For more information, visit the geWorkbench project page.
The software can be downloaded.
caIntegrator can extract the genomic data from caArray hosted on either a private server can:
The current release of caIntegrator, version 1.4, works with caArray 2.5.
To install a local copy, download a copy of the software.
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.
The GenePattern team has recently devleoped caArray2ImportViewer, a visualizer to import data from caArray into GenePattern. It is compatible with caArray 2.4.0.x. Please see the documentation to learn more.
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.
