Cyclic peptide design issues

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

Start by reviewing the reported run command, especially /data/RFdiffusion/scripts/run_inference.py, the 7zkr_GABARAP.pdb input, and the cyclic and chain-related options. Reproduce the command with the sample input and inspect the generated outputs and logs to determine whether cyclic structures are being requested and produced. Done means identifying whether this is a script/configuration problem and documenting the evidence.
