We employed 3stage design protocol (100,100,20) from ColabDesign with our FoldCraft loss for AF2-Multimer hallucination. Only FoldCraft loss was used for design without other AF2 loss functions. ProteinMPNN model with temperature 0.1 generated 2 sequences per designs. The design algorithm was set in loop until we got at least 100 binder passing BindCraft filters.
