About the EXALT Site

 Welcome to EXALT, a resource for examining gene expression signatures in public domains. A gene expression signature in a microarray data set
 is defined by EXALT as a list of significant genes with their group comparison codes and corresponding statistical scores. In essence,
 a signature represents a statistically validated ‘fingerprint’ associated with a biological observation made from a gene expression experiment.
 EXALT has extracted signatures of differential genes within each experiment and built a large formatted collection of microarray results
 from NCBI GEO and published cancer studies. Thus, investigators can focus on discovery by searching, browsing, and querying on pre-computed
 gene expression signatures.

EXALT Main Features

The best performance of EXALT web site has been tested in IE6.0 or above.  

THE IMPLEMENTED FEATURE: Extract signatures of your own data set and search for homologous data datasets by clicking
Uploading a query data set.  [How do I ...].

THE FEATURE UNDER DEVELOPMENT: Access thousands of signatures with rich annotations by
using search entry tool bar (“Search A Database … for … GO  Clear”) or click “Browsing data sets“ on the menu bar.
