Correlative search

Correlative search finds probes with similar expression profile to the selected seed probe over all samples within a user-specified structure. Pearson's correlation coefficient is computed for all probes and results ranked in descending order.

Image Added This correlative search function can be access through the Web application or using the RMA Services and PipesAPI.
