When merging a commit to master, you need to increase the version number in czid_pipeline/version/__init__.py:

• if results are expected to change, increase the 2nd number
• if results are not expected to change, increase the 3rd number.

• 1.8.7

  • Bug fix for count_reads and non-host read counts.

• 1.8.4 ... 1.8.6

  • Minor code quality, documentation, and logging improvements.

• 1.8.0 ... 1.8.3

  • Upload a status file that indicates when a job has completed.
  • Add a dedicated semaphore for S3 uploads.
  • Code quality and documentation improvements.
  • Restore capability to run non-host alignment from the development environment.
  • Try a more relaxed LZW fraction if the initial filter leaves 0 reads

• 1.7.2 ... 1.7.5

  • General code style changes and code cleanup.
  • Convert string exceptions and generic exceptions to RuntimeErrors.
  • Change some print statements for python3.
  • Add more documentation.

• 1.7.1

  • Truncate enormous inputs to 75 mil paired end / 150 mil unpaired reads.
  • Support input fasta with pre-filtered host, e.g. project NID.
  • Many operational improvements.

• 1.7.0

  • Add capability to further filter out host reads by filtering all the hits from gsnapping host genomes. (i.e. gsnap hg38/patron5 for humans).

• 1.6.3 ... 1.6.1

  • Handle bogus 0-length alignments output by gsnap without crashing.
  • Fix crash for reruns which reuse compatible results from a previous run.
  • Fix crash for samples with unpaired reads.
  • Improve hit calling performance.

• 1.6.0

  • Fix fasta downloads broken by release 1.5.0, making sure only hits at the correct level are output in the deduped m8.
  • Fix fasta download for samples with unpaired reads by eliminating merged fasta for those samples.
  • Extend the partial fix in release 1.5.1 to repair more of the broken reports. Full fix requires rerun with updated webapp.
  • Correctly aggregate counts for species with unclassified genera, such as e.g. genus-less species 1768803 from family 80864.
  • Fix total count in samples with unpaired reads (no longer doubled).
  • Fix crash when zero reads remain after host filtering.
  • Fix bug in enforcing command timeouts that could lead to hangs.
  • Fix performance regression in stage 2 (non-host alignment) introduced with 1.5.0.
  • Deduplicate and simplify much of stage 2, and improve performance by parallelizing uploads and downloads.

• 1.5.1

  • Fix bug introduced in 1.5.0 breaking samples with non-species-specific deuterostome hits.

• 1.5.0

  • Identify hits that match multiple species within the same genus as "non species specific" hits to the genus.

• 1.4.0

  • Version result folder.

• 1.3.0

  • Fix bug causing alignment to run before host subtraction in samples with unpaired reads.
  • Include ERCC gene counts from STAR.

• 1.2.0

  • Synchronize pair order after STAR to improve sensitivity in 10% of samples with paired-end reads.
