This module does not support conda, as the bioconda doubletdetection build is not working properly.

Hey @LeonHafner how did it get built by Seqera containers then? What's was in the environment.yml?

Was it

channels:
  - conda-forge
  - bioconda
dependencies:
  - conda-forge::anndata=0.10.7
  - conda-forge::louvain=0.8.2
  - bioconda::doubletdetection=4.2

Hey @edmundmiller,
the Seqera containers are built using the doubletdetection package via pip. However, nf-core linting doesn’t allow pip dependencies in the environment.yml. To address this, I added the package to Bioconda, but after some painful hours of debugging and trying to match the versions with the containers, it turned out the Bioconda version is broken and isn’t working as expected.
