Cyclic peptide design issues

Open zzxchelly opened this issue 3 months ago • 2 comments

Hello, I'm a beginner and would like to use RFpeptides to design cyclic peptides that bind to my target protein. I've generated over 2,000 structures for my target protein, but none of them have resulted in a cyclic peptide. I'm worried it might be a script issue. I used the official sample input PDB and the script twice to generate a total of 20 structures, but still haven't found a cyclic peptide. Could you please help me check the following to see if this is a script issue?

#!/bin/bash

prefix=/data/*/job1/output/new_cyclic_binder

num_designs=10

pdb='/data/*job1/7zkr_GABARAP.pdb'

HOTSPOTS='["A51","A52","A50","A48","A62","A65"]' script="/data/RFdiffusion/scripts/run_inference.py" $script --config-name base
inference.output_prefix=$prefix
inference.num_designs=$num_designs
'contigmap.contigs=[12-18 A3-117/0]'
inference.input_pdb=$pdb
+inference.cyclic=True
diffuser.T=50
+inference.cyc_chains='a'
+ppi.hotspot_res=$HOTSPOTS

This issue discusses the same problem. It seems that for some people reconfiguring the SE3 environment helped.
