Upload initial Structure A in PDB format:

Enter final Structure B:




Enter chain ID and the range of residues (by index number) to undergo dihedral angle moves (e.g. "A,22,33" = move residues 22-33 on Chain A, put each range on a separate line, and use chain ID = A if none exists):

Enter chain ID and range of residues (by index number) whose final positions should match reference structure (enter same as above, but not yet fully implemented):

Choose movetype: . φ,ψ noise level (in degrees) =

Sample ω angle: noise level (in degrees) =
