Search for data sets of interest

Search accession numbers Multiple accessions can be separated by commas. Try GSE63462,SRP070529,SRR401430 for A. thaliana.


Search for keywords Case-insensitive.
Try "ethanol" for S. cerevisiae.

More sophisticated keyword searches can be done at GEO and SRA, to identify studies and accession numbers of interest.

Keyword searches in mouse and human take up to a minute to complete.
