In this PR, I'm trying to fix this issue: ensembl-vep refseq/merged option broken.

Let's assume these param values:

vep_cache: path/to/vep_cache_dir
vep_cache_version: "111"
vep_genome: GRCh37
vep_species: homo_sapiens
vep_custom_args: "--everything --format vcf"

As of sarek 3.4.2, we can feed custom VEP options via params.vep_custom_args to the pipeline.

If --refseq or --merged is in params.vep_custom_args, it will be passed to VEP's final command, and result in the following effects:

  • If --refseq is provided, VEP will use ${vep_cache}/${vep_species}_refseq/${vep_cache_version}_${vep_genome} as the annotation source
  • If --merged is provided, VEP will use ${vep_cache}/${vep_species}_merged/${vep_cache_version}_${vep_genome} as the annotation source

Reference: https://useast.ensembl.org/info/docs/tools/vep/script/vep_options.html

When this happens (Let's assume --refseq is in params.vep_custom_args), in the ANNOTATION_CACHE_INITIALISATION workflow, a wrong vep_cache_path_full path will be tested if exists, because it won't check if params.vep_custom_args contains --refseq.

I modified the related code such that in the ANNOTATION_CACHE_INITIALISATION workflow, vep_cache_path_full will be built correctly by taking into consideration if --refseq or --merged is present in params.vep_custom_args.

I've tested with in-house data, and it worked as expected: when --refseq is present, VCF files will be annotated with RefSeq cache (e.g. "homo_sapiens_refseq/111_GRCh37"); when neither --refseq nor --merged is present, they will be annotated with normal cache (e.g. "homo_sapiens/111_GRCh37).

PR checklist

  • This comment contains a description of changes (with reason).
  • If you've fixed a bug or added code that should be tested, add tests!
  • If you've added a new tool - have you followed the pipeline conventions in the contribution docs
  • If necessary, also make a PR on the nf-core/sarek branch on the nf-core/test-datasets repository.
  • Make sure your code lints (nf-core lint).
  • Ensure the test suite passes (nf-test test tests/ --verbose --profile +docker).
  • Check for unexpected warnings in debug mode (nextflow run . -profile debug,test,docker --outdir <OUTDIR>).
  • Usage Documentation in docs/usage.md is updated.

I changed the signature of ANNOTATION_CACHE_INITIALISATION workflow, resulting this error (which is expected because I passed an additional parameter params.vep_custom_args to it)

ERROR ~ Workflow `NFCORE_SAREK:ANNOTATION_CACHE_INITIALISATION` declares 10 input channels but 11 were given

If adding a new parameter to this workflow is ok, I guess we need to change the declarations to 11?

Nevermind, I forget one line of code.
