Database of curated and re-analyzed gene expression studies

Gemma provides data, experimental design annotations, and differential expression analysis results for thousands of microarray and RNA-seq experiments. We re-analyze raw data from public sources (primarily NCBI GEO), annotate experimental conditions, conduct quality control and compute differential expression using standardized procedures. We have especially good coverage of experiments relevant to the nervous system. See the documentation for more information. Gemma was and developed and is maintained by the Pavlidis group at UBC.
