The command of each process doesn’t seem to be recognized — I checked the .command.err log files, and they have the command not found error. Could you help me understand this problem?
It doesn’t solve the problem. Can it be because I installed TractoFlow with nextflow pull scilus/tractoflow instead of downloading the singularity container?
Tractoflow needs a container to run with.
Using nextflow pull you downloaded the software but it needs the whole environment to work with. You can use singularity or docker, either way you choose is described in the documentation.
