Dear Dr Case,
thank you very much for your answer. Using ptraj's strip option, I get polypeptides without proper termini (missing OXT) due
to truncation of adjacent amino acids; xleap sets the missing termini of the chosen residues automatically, so I get different
numbers of atoms in my trajectory (obtained with ptraj) and the prmtop-file, hence sander and nmode give error messages.
Should I convert all my snapshots from the trajectory to inpcrd-files that come along with the prmtop-files in xleap to get
starting structures for the minimisation/entropy calculations? Or what should I do?
Best regards,
Martin
