conda
Issues with conda:
- bioconda channel is not added by default (see this issue on github,
- conda singularity recipes does not work when trying to run the image (build works but when running as a basic user (not root), conda is installed in /usr/local and singularity is trying to write into a tmp directory in /usr/local).
Maybe a more complex conda recipe would work: https://github.com/sylabs/singularity/issues/5075 Indeed, I think conda needs at least to create and initiate an environment.
Moreover, we could automate the runscript line to fit the conda installed program or add a %app dedicated section.
