Error when providing a bwameth index (MethylSeq v2.4.0 and v2.5.0)

[bioinfoMMS]

Description of the bug

I am running into an error regarding bwameth indexing/aligning. I am trying to get the bwameth pipeline to work with an existing bwameth index. Looks like there have been similar problems, but I haven't seen how to fix this.

Command used and terminal output

#Command:

nextflow run nf-core/methylseq -r 2.4.0 --input samplesheet.csv --outdir /corestore/mmacd/nextflow --fasta /corestore/mmacd/nextflow/methylation_twist_panel/references/hg38.fa --fasta_index /corestore/mmacd/nextflow/methylation_twist_panel/references/hg38.fa.fai -profile singularity --aligner bwameth --bwa_meth_index /corestore/mmacd/nextflow/methylation_twist_panel/references/

@bioinfoMMS Not sure if you are still facing this issue, but I also ran into this, and think it is related to the fact that we both have our reference files in a subfolder (e.g. references). The touch command as is isn't recursing through the references subfolder and modifying the timestamps.

I resolved this by fixing the line with the touch command to this:

touch -c -- references/*
