Free Microarrays intersection to expand your discovery

Post by cudream » Fri Jul 08, 2011 1:37 am

Dear colleagues,

We would like to introduce a new tool called “CU-DREAM” for intersecting two microarray datasets. CU-DREAM compares the datasets of two microarray experiments (reported in with different conditions to determine if the two conditions share genome wide gene regulation pathway. CU-DREAM is an effective tool for the pre-screening of drugs, substances or environmental insults or the identification of the genetic changes that are associated with pathological conditions. For more information please find the CU-DREAM article at ... ew/589/431

CU-DREAM(X) can intersect a GSE dataset with “a gene set.” This program is designed to find the association between up or down regulation of certain GSE microarray experiments and a group of certain genes. Example of CU-DREAM(X) comparing gene expression and gene containing intragenic LINE-1 (long interspersed nuclear element-1) can be found at ... ne.0017934

All materials (executable file, user manual, examples) can be downloaded at the project homepage:

Please reference CU-DREAM and CU-DREAM(X) as follow.
