The open-source, open-access software tool, caArray version 1.0, developed by 
the NCI Center for Bioinformatics (NCICB), can be used to create public repositories of
microarray data, linking scientists within an institution or around the globe.

the software is compatible with other tools created for 
the cancer Biomedical Informatics Grid, or caBIG (http://caBIG.nci.nih.gov),
