Hi All! I met a problem when I tried to run the design_macrocyclic_binder.sh in the example directory of rfdiffusion, Any advise?Thanks for any reply!

Thank you for bringing this up! This is actually a bug introduced from a recent merge. I just created PR #409 that introduces a fix. We should get a permanent fix merged soon.

Thanks a lot. After adding ({"idx_pdb": sampler.idx_pdb} if hasattr(sampler, "idx_pdb") else {}), the issue was resolved.
