Data Release Tracker

CRAM CONVERSION
As of September 15, 2025, all released BAMs have been converted to CRAMs for optimal file storage at the DAC. The data release tracker will start to announce new CRAMs as they are released.

Announcements

Attention: BAM changeJul 23, 2025
As of July 8, 2025, DAC will release BAM files without the BI and BD tags, which were originally added after base quality recalibration (BQSR).
Data RetractionMar 10, 2025
One WGS ONT PromethION 24 BAM from COLO829-BLT50, SMAFIPHR8QOG, has been retracted due to sample swap.

Attention Users
The V1 Benchmarking data portal will be open to SMaHT consortium members only at this time.
Data-related news
  • The raw sequence files, i.e. unaligned BAM and FASTQ, and the data from the benchmarking tissue samples that were not distributed by TPC will be available upon request at this time (through Globus).
  • The SMaHT Data Portal, V1 Benchmarking release, now makes benchmarking data available for download for authenticated consortium members. Users can continue to obtain the access keys for metadata submission.
