Hi,
Currently DepMap omics is offering data on both ModelID (ACH-xxxxxx) and ProfileID (PR-xxxxxx) levels to enable more granular data sharing. Specifically, in the download page, everything ending with the suffix “Profile” has ProfileIDs as the identifier.
If you are looking for a way to map ProfileIDs to ModelIDs, OmicsProfiles.csv should be the file you need, and Model.csv might be relevant too if you are looking for cell line name and/or metadata information.
Hope this helps!
Simone
