l1000.db: SQLite database of LINCS L1000 metadata

Download (4.67 GB)
LINCS L1000 measures the transcriptional response to perturbation. `l1000.db` is a SQLite database that we use to store LINCS L1000 data. Our database contains several parts of the L1000 resource that have been converted into user-friendly tables. The database also provides information not available from L1000. Namely, we computed the chemical similarities between L1000 compounds and mapped the L1000 compounds to external vocabularies.

+ The `cells` table contains the L1000 cell lines.
+ The `sigs` table contains the L1000 signatures.
+ The `perts` table contains the L1000 perturbations.
+ The `similarity` table contains chemical similarity scores for all compound pairs.
+ The `unichem` table contains a mapping of L1000 compounds to external chemical vocabularies.

This database does not contain the L1000 expression data, hence we consider it metadata. `l1000.db.bz2` is bzip2 compressed to reduce file size. Decompress before use.

We rely on this database when computing consensus signatures for perturbations.
