ArrayExpress – functional genomics data
ArrayExpress Archive of Functional Genomics Data stores data from high-throughput functional genomics experiments, and provides these data for reuse to the research community.
26 February 2022 - ArrayExpress collection now released in BioStudies
The transition phase has begun! The ArrayExpress collection is now live in BioStudies. Head over to BioStudies and explore the new look of the archive, study pages, search filters and download functionality.
Here is an example: Current: E-MTAB-7871 New: E-MTAB-7871
Note that not all datasets have been migrated from ArrayExpress to BioStudies yet, so you may not find a particular experiment and search results will differ.
A quick summary of the changes to expect:
- Programmatic data access will be available via the BioStudies API
- Data download from FTP archives will change to BioStudies paths and functionality (e.g. adding Aspera download)
- Post-submission modifications will be managed via the BioStudies submission tool (this is not yet available during the transition phase!)
- All accession numbers will remain valid, and web links will be redirected
- Annotare will remain the submission tool for adding new data
- Study search powered by ontology expansion
