fine. There are other things I suggested you look at; you haven't ruled out that something else went wrong along the way or that your peptide doesn't have the net charge you think it does.<br>> <br><br>Actually, no it doesn't. You don't have any space between the moleculetype name ("NA+") and the number of molecules. This line isn't being read correctly, which might be your problem, though I'm shocked that you're not getting some other error about a missing number of molecules or number of coordinates not matching the topology.<br><br>-Justin<br><br>-- ========================================<br><br>Justin A.
