Method & evidence

Generate one deterministic 20–50-residue protein backbone with the RFdiffusion Base model.

Scope & limitations

  • This tool supports unconditional Base-model generation only; target-conditioned and symmetry modes are not available.
  • Backbone generation may take tens of seconds to minutes.

Interpreting results

  • The output is an unconditional backbone proposal, not a sequence, binder, motif scaffold, or experimentally validated structure.
  • Review geometry and add sequence-design and validation steps before experimental use.
  • Compare repeats only when the model version, length, step count, and seed are identical.

Input requirements & outputs

Input checks

  • Length from 20 through 50 residues
  • Diffusion steps from 15 through 50
  • Exactly one design with deterministic seed 0

Expected results

  • Predicted backbone structure — Open the PDB and inspect residue count, backbone atoms, and coordinates.
  • Generation settings — Review backbone length, diffusion steps, seed, and model alongside the structure.
