13 October 2017 - ArrayExpress is stopping import of GEO data

Unfortunately, we are stopping the regular imports of Gene Expression Omnibus (GEO) data into ArrayExpress. We will keep using data from GEO to build our added value database Expression Atlas, and the reprocessed and additionally annotated data for selected datasets will be available from there.
