6.2.1

TBProfiler Container

Main tool: TBProfiler

The pipeline aligns reads to the H37Rv reference using bowtie2, BWA or minimap2 and then calls variants using bcftools. These variants are then compared to a drug-resistance database. It also predicts the number of reads supporting drug resistance variants as an insight into hetero-resistance.

Database

This tool relies on a database to run. The version (AKA git commit hash) of the database that is included in the docker image is 97b5876. This is from the GitHub repository https://github.com/jodyphelan/tbdb. This can be confirmed in the json file: /opt/conda/share/tbprofiler/tbdb.version.json:

$ grep 'commit' /opt/conda/share/tbprofiler/tbdb.version.json
{"name": "tbdb", "commit": "5f3c51e", "Merge": "b1a2549 abddb8e", "Author": "Jody Phelan <[email protected]>", "Date": "Thu Jan 19 10:47:32 2023 +0000"}

Additionally you can run the command tb-profiler list_db to list the same information

$ tb-profiler list_db

Updates

Release 5.0.1 implemented sqlite3 database locking with https://py-filelock.readthedocs.io/en/latest/index.html. This should fix issues using it over network filing systems (NFS). For more information, official documentation can be found here.
