Linking to the Gene Expression Atlas

Gene links

You can link directly to information about the expression of genes in the Atlas using certain gene identifiers and Gene Ontology (GO) terms in a URL link. The gene identifiers that can be used include Ensembl, EMBL/GenBank, UniGene, UniProt and RefSeq identifiers. The complete list of identifiers and terms that can be used can be found in the following text file: gene_identifiers.txt.

The format of a URL link to the Atlas is as follows:

http://www.ebi.ac.uk/gxa/gene/IDENTIFIER

If the identifier matches one single gene (e.g. ENSMUSG00000000701) then the gene view page for the gene will be returned. This provides a one-page summary of Atlas information about a given gene. See the Atlas help pages for more information.

If the identifier matches more than one gene (e.g. GO:0032094) then a heat map view of the results for all the genes that link to the identifier will be shown. See the Atlas help pages for more information.

Experiment links

You can also link directly to an Atlas experiment knowing the experiment accession (e.g. E-MEXP-1014). The format of a URL link to the Atlas Experiment View is as follows:

http://www.ebi.ac.uk/gxa/experiment/ACCESSION

Programmatic Access

For information about creating complex queries of the Atlas programmatically see the Atlas programmatic access help pages.
