I am trying to run MEGARes (AMR++2) test according to their instructions (https://github.com/meglab-metagenomics/amrplusplus_v2/blob/master/docs/installation.md) and getting the error below...

nextflow run main_AmrPlusPlus_v2.nf -profile singularity --output test_results

Tip: you can try to figure out what's wrong by changing to the process work dir and showing the script file named `.command.sh`

Where are the errors? How can I solve it?

Thanks in advances
