Backbone designs
Diffusion steps
Contig map
RFdiffusion contig string without the brackets. For example 150-150 for an unconditional monomer, 5-15/A10-25/30-40 to scaffold a motif, or B1-100/0 100-100 for a binder.
Input PDB (optional)
Required by any contig that references chains of a structure.
Hotspot chain (optional)
Hotspot residues (optional)
Comma- or space-separated residue numbers on hotspot_chain, e.g. 100,101,102.
Target PDB
Target chains
Comma-separated chain IDs from the target PDB to keep as context.
Binder length range
e.g. 70-100.
Target hotspots (optional)
One "chain: residues" per line, e.g. "A: 20 21 23".
Target-binder complex PDB
Hotspot chain (optional)
Hotspot residues (optional)
Comma- or space-separated residue numbers.
Binder chain
Designed residues
Comma-separated ranges on binder_chain to regenerate; everything else on it stays fixed.
Designed lengths (optional)
One length range per designed_residues range, e.g. 5-9,3-8,10-25. Blank keeps each span's original length.
Motif source PDB
Motif chain
Motif residues
Comma-separated ranges of the motif to preserve.
Scaffold gap lengths (optional)
One range per gap (one more than the number of motif ranges), e.g. 10-40,10-40,10-40. Blank defaults every gap to 10-40.
Starting structure PDB
Chain to partially diffuse
Diffused residues
Comma-separated ranges on designed_chain to noise; other residues (and other chains) stay fixed.
Keep sequence fixed at (optional)
Comma-separated ranges, in designed_chain's own residue numbering, to hold sequence identity constant even while noised.
Partial noising steps
Target PDB
Desired binder fold PDB
A structure whose secondary-structure/block-adjacency pattern the new binder should follow.
Hotspot chain (optional)
Hotspot residues (optional)
Symmetry
e.g. C2, C4, C6, D2, tetrahedral, octahedral, icosahedral.
Total oligomer length
Divided evenly across the symmetric copies by RFdiffusion.
Guide with an inter/intra-chain contact potential
Structure containing the symmetric motif copies
Symmetry
Motif copies
Comma-separated per-copy residue ranges, one per symmetric unit.
Scaffold residues before each copy
Scaffold residues after each copy
Guide with an inter/intra-chain contact potential
Model checkpoint override (optional)
Default (Base_ckpt.pt)
Active site (small motifs)
Complex base (target + binder)
Complex + fold conditioning
Inpaint sequence
Inpaint sequence + fold conditioning
Base, epoch 8 (symmetric motifs)
CA noise scale
Frame noise scale
Custom guiding potential (optional)
Raw potential spec, e.g. "type:substrate_contacts,s:1,r_0:8,rep_r_0:5.0,rep_s:2,rep_r_min:1".
Substrate CCD code (optional)
Only used with a substrate_contacts potential, e.g. LLK.

Guide decay
constant
linear
quadratic
