nf-core/methylseq

v1.6.1 - 2021-05-08

Pipeline Updates

  • Added new config profile to run minimal test paired-end dataset, with -profile test_paired. Added to the CI tests.

v1.6 - 2021-03-26

⚠️ Breaking change!

In line with a standardisation change across all of nf-core, we have changed the main parameter name for supplying files to the pipeline. In this release, please use --input instead of --reads. The parameter still works in the same way as before.

    • Sets bismark_maxins = 1000, clip_r1 = 8, clip_r2 = 8, three_prime_clip_r1 = 8, three_prime_clip_r2 = 8
  • New --publish_dir_mode parameter to customise results folder behaviour
  • Fix bug on AWS for bismark_hisat known splice file (#177)
  • Moved parameter documentation into new nextflow_schema.json file
  • Added a -profile test_full config for running the pipeline with a full-size test dataset
    • See the config file for details
    • This will be used for automated release tests on AWS, results browsable on the website

  • Fix --rrbs mode (#24)
