Dear all, I tried to use the script shown in Wiki "Missing residue" section to automatically fill a gap of 12 residues in a file PDB. However, the application stops with the error message: "No loops detected for refinement: you must redefine select_loop_atoms". I had a look at the archive and found that 12 residues is the upper limit for loop detection and refinement, therefore I don't know why Modeller 9v4 does not work in my case. Does anyone have suggestions? Many thanks and best regards Anna
