Encyclopedia of DNA Elements (ENCODE)

BED (Browser Extensible Data) Files

The ENCODE dataset contains information for approximately 7000 experiments along with 14,000 BED files collected by The Encyclopedia of DNA Elements (ENCODE) Consortium. Examples of experiment metadata captured include the target biosample, assay type, gene assembly, etc. Bed files link to individual bed lines, which state the genomic position of individual peaks. Data Commons ingested all experimental data in BED format.

Data made available under: ENCODE Data Use Policy for External Users. This data was formatted for Data Commons through a collaboration with Dr. Anthony Oro’s group at Stanford University.

Genotype-Tissue Expression (GTEx)

GTEx Analysis V8

The GTEx eGene and significant variant-gene association data were generated from samples “collected from 54 non-diseased tissue sites across nearly 1000 individuals, primarily for molecular assays including WGS, WES, and RNA-Seq. Remaining samples are available from the GTEx Biobank.” The single-tissue cis-eQTL data from the v8 release was used. Due to the size of the datasets only Skin - Not Sun Exposed and Skin - Sun Exposed are made available on the main graph. The data for all tissues can be accessed on the Biomedical Data Commons knowledge graph.

GTEx is an NIH human genomic data unrestricted-access data repository and the data was made available in compliance with GTEx Data Release and Publication Policy. GTEx outlines how to cite use of GTEx data in journal publication.
