Error_during_installation

[vishramt7]

Description of the bug

Hi,
I am trying to install this pipeline using conda. The command used is mentioned below. Conda is expecting an environment.yml file to be present inside "raredisease/modules/local/" folder. This environment.yml is missing from the git repository. How can I solve this issue ?

Command used and terminal output

Command: nextflow run main.nf -profile test_one_sample,conda --outdir install -resume

ERROR ~ Error executing process > 'NFCORE_RAREDISEASE:RAREDISEASE:CALL_SNV:POSTPROCESS_MT_CALLS:ADD_VARCALLER_TO_BED (1)'

Caused by:
  Conda environment file does not exist: /home/diagnostics/pipelines/raredisease/./workflows/../subworkflows/local/./variant_calling/../../../modules/local/environment.yml

Indeed, the `environment.yml-file seems to be missing. It might be that the pipeline has not been very well tested with conda. (It is my impression that very few people use conda for running the nf-core pipelines.)

I tried running a very similar command:

nextflow run nf-core/raredisease -r 2.0.1 -profile test_one_sample,conda --outdir results

with nf 23.10.1, but got:

ERROR ~ mapping values are not allowed here
 in 'reader', line 2, column 15:
        cut: Usage: cut
                  ^

That doesn't seem to be a problem if I use singularity or docker. @vishramt7 : Could you reproduce the error for singularity or docker?

Hi @asp8200,
Thanks for the reply! I want to avoid docker/singularity so I chose conda. This seems to be a conda specific issue.
I faced the same error as posted by you. This was due to a line of code trying to print the version of the "cut" command.

It seems that the raredisease-pipeline doesn't support conda 🤔 I can try to fix the issue with the missing environment.yml-files, but there might be other issues related to conda.

The error

ERROR ~ mapping values are not allowed here

        cut: Usage: cut

comes from the "version-statement" in modules/local/get_chrom_sizes.nf, right?

Hi @vishramt7 and @asp8200,
You're right that the conda part isn't that well tested as we've had issues getting some tools to run with conda, the SNV/INDEL caller deepvariant being one of them. cut should of course work though.

Right you are, @jemten. After just locally fixing the issue with the missing environment.yml-files, I run into this:

The only alternative to deepvariant in the raredisease-pipeline is sentieon-dnascope, right?

It seems that deepvariant can be skipped by setting the params.variant_calller to blank, but then perhaps there isn't much point in running the pipeline?

Hi @asp8200 ,
Yes, that's right

[asp8200]

So I tried setting params.variant_caller to blank, but the pipeline eventually failed with:

Hi @jemten and @asp8200,
Does this mean that this pipeline can only be installed and executed using docker/singularity ?

[jemten]

At this moment, yes. It is stated in the prerequisites in the usage doc (https://github.com/nf-core/raredisease/blob/master/docs/usage.md#prerequisites) but we can add to the README as well. It would be nice to add the GATK variantcalling subworkflow from sarek and/or getting deepvariant to run with conda as well but we're not there yet.

[asp8200]

@vishramt7 : Since you got conda on your system, perhaps you can just conda-install singularity? (That seems to work on my system.)
