Dear TCGA Colleagues, The December 2011 Firehose analysis run has been uploaded and will be available in the tcga4yeo tree pending internal mirroring by the DCC. This analysis run was based upon version 2011_12_30 of the Firehose stddata package, and is described in more detail on our dashboard at https://confluence.broadinstitute.org/display/GDAC/Status-Analysis+Runs As our release notes indicate, mutation significance results for LUSC and LUAD have been removed from this analysis run, due to discrepancies observed between the set of genes identified as most significant by MutSig v1.5 (currently installed in Firehose) versus the set manually curated by the TCGA lung AWG. Our aim is to address this discrepancy by installing MutSig v2 as soon as possible. If you have any questions or comments please do not hesitate to send them to our gdac@broadinstitute.org mailing list. Regards, Michael S. Noble
