Dear All I am trying to study inter peptide interaction fpr which I need to put more than one peptide in one simulation box. I did it with genconf command but this inserts peptide in a regular ordered manner I want these to be in irregular disordered insertion. Even after using genconf , I tried to proceed furthe after solvation with spc water. The energy minimization (steepest descent) failed to converge even after 5000 steps and theirafter position restraint dynamics failed giving segmentation fault. Introducing more peptide after generating .gro with -ci -nmol gives error showing more than one residue in insert molecule. Please help me and write commands which I should follow. Shahid Nayeem
