Description

I have an antigen-antibody complex structure, and I performed diffusion on part of the antibody sequence. The current parameters are as follows, but the result connects the two chains of the antibody together. How should I modify the parameters?

run_inference.py inference.output_prefix=rfd_diffuser20/test inference.input_pdb=test.pdb 'contigmap.contigs=["228-228/0 C229-503"]' diffuser.partial_T=20 inference.num_designs=1000 'contigmap.provide_seq=[0-29,31-227]' 'ppi.hotspot_res=[C262,C263,C265,C266,C267,C268,C269,C270,C315,C316,C317,C319,C321,C329,C344,C345,C346,C348,C374,C375,C376,C377,C393,C395,C397,C399,C434,C435,C436,C437,C438,C451,C455,C457,C458,C459,C460,C462,C465,C467,C469]'

Research direction

Start with run_inference.py and reproduce the supplied command using test.pdb. Read the contigmap, provide_seq, ppi.hotspot_res, and diffuser.partial_T configuration documentation or entry points, then inspect how the antibody chains are represented and connected. Done means identifying a parameter configuration that preserves the intended chain separation and documenting the reproducible command.
