This is a beta version of the new COSMIC Downloads page. The new page and the download files available here have been re-designed to improve useability and accessibility. It is now possible to browse by project and download complete datasets for all available products and genome versions for the current and 3 previous releases – COSMIC, Cell Lines Project, Actionability, and Cancer Mutation Census (CMC).

A detailed technical document listing all the changes in the new download files, along with the ERD (Entity Relationship Diagram) to explain the links between different products and a list of all the COSMIC identifiers is available in the change log.

To help transition to the new files we are supporting the legacy downloads for a year (i.e. for v98 and v99), but thereafter these downloads will be discontinued. Until then access to the legacy downloads is available from the “Archive Downloads” page.

We value your feedback on the new Download page and download files. Please help us as we work to improve the useability and accessibility of COSMIC data by sending your thoughts to cosmic@sanger.ac.uk

We have made the first 100 lines of each of the download files freely available so you can try out the data. More information can be found on our About page.
