I'm getting the following RuntimeError when trying to run ProteinMPNN on a windows machine with Python 3.7. The method I'm using works with the example 6 inputs, but when I try to use my own protein structure 4rjj, I get the runtime error: RuntimeError: Class values must be smaller than num_classes. I've tried using the biological assembly downloaded directly from the pdb and removing the ligands and all non "ATOM" lines from the structure but I still get this error message.
The following command works, but I would like to model it as a homooligomer and fix some residues.
py protein_mpnn_run.py --path_to_model_weights "C:\ProteinMPNN\vanilla_model_weights" --pdb_path 4rjj.pdb --pdb_path_chains "A B C D" --out_folder "C:\ProteinMPNN\myoutputs\4rjj" --num_seq_per_target 20 --sampling_temp "0.1 0.2 0.3" --batch_size 1 --omit_AAs='XC'
Also, when I use the helper scripts, I need to remove the path ("C:\ProteinMPNN\my_input_PDBS\" in the text below) from the jsonl files or I get the following error message: OSError: [Errno 22] Invalid argument: 'my_outputs_directory//seqs/C:\ProteinMPNN\my_input_PDBS\4rjj.fa'
