Hi, thanks for opening the issue. It seems that there is a problem on your Ubuntu 20.04.2 machine to create the bioconda cnvkit env.

Can you try to verify this by running:
conda create --mkdir --yes --quiet --prefix /home/ubuntu/test_cnvkit bioconda::cnvkit=0.9.9

Would it be possible for you to test the pipeline on a CentOS 7 AWS instance? We are running CentOS 7.9 locally, and there we do not see this issue. Debian 10 seem also to work.

We have to look into this, however we are not providing the bioconda packages.

I just checked on a vanilla Ubuntu 20.04.3 docker image and it seems that the cnvkit conda installation is working.
Please make sure that you add the following conda channels before running the pipeline:

conda config --add channels defaults
conda config --add channels bioconda
conda config --add channels conda-forge

I hope this solves your problem

Adding bioconda and conda-forge to channels solved the issue. Thanks!

Sorry, gonna reopen this one as it seems to be still issue with the environments. This time its the process RegionsBedToIntervalList
Here is the message

Here is once again a complete log:
nextflow.log

[riederd]

I'm sorry that you ran again into an issue.
Can you edit the /home/ubuntu/nextNEOpi/assets/nextNEOpi.yml
and replace
bioconda::pysam=0.16.0.1 with bioconda::pysam=0.16

Let me know if that works

[aneichyk]

seems to have solved the installation, but I now have an issue with CPU requirements:

  Process requirement exceed available CPUs -- req: 34; avail: 16

I tried to find where task.cpus is defined, but it doesn't seem to be in the conf/ folder or in the nf file. Could you point me to where is it defined?

Do you want me to open a different issue for this?

[riederd]

please look into conf/process.config you can adjust the number of cpus there for all multithreaded processes. I think in your case it is the BWA process.

[riederd]

In the README we state:

Before running the pipeline, the config files in the conf/ directory may need to be edited. In the params.config parameters default settings are defined. The process.config is a template for the configuration of the single processes, you may check the number of CPUs assigned for each process and adjust according to your systems capabilities.

Anyway, we lower the number of cpus in that default config in the next release.

[riederd]

I'm going to close this issue for now, We just released nextNEOpi_v1.2.1 that should fix the problems. Thanks again.
