Welcome to OMics Compendia Commons (OMiCC)

Update log:

Dec 2020: The database has been synchronized with GEO to June 2020

Jul 2019: The database has been updated with GEO to January 1st 2019. Recount2 RNA-seq datasets have been added to OMiCC

Oct 2017: The database has been synchronized with GEO to April 2017. Also the Restful API support has been added

OMiCC is a community-based, biologist-friendly web platform for creating and (meta-) analyzing annotated gene-expression data compendia across studies and technology platforms for more than 40,000 human and mouse studies from Gene Expression Omnibus (GEO) and RNA-seq studies exported from recount2. An important feature of OMiCC is that it allows users to contribute to the community by sharing meta-data essential for data collation, reuse, and (meta-) analysis across studies. Thus, users of OMiCC can reuse sample groupings and pairings created by other users to construct cross-study data sets. We envision that as more users take advantage of OMiCC to perform biological hypothesis generation and discovery, more users will create and share such meta-data as well as data compendia and analyses with the biomedical research community.
