Dear Mark,
Thank you for your reply
I have used the peptide FXXXXLF
For that pdb2gmx construct topology successfully with -ter choosing any thing
for both terminal.
OK, well you can work with that topology as your template for the same
kind of procedure, but you will have to pay attention to the atom types
of the N terminus of F (both N and its hydrogen atoms). They should
match those of the N terminus of the C-terminal N in FXXXLF.
But When i Choose none with -ter for both terminal It again shows error as
follows
Fatal error:
There is a dangling bond at at least one of the terminal ends. Select a proper
terminal entry.
Shrug. You're not giving your pdb2gmx commands, any useful diagnostic
output before the error message, or any information about the terminal
residues, so you're making your own life hard by making every one's hard.
Mark
For your Convenience i have pasted the previous discussion
That suggests you have a problem with your coordinate file that is
independent of your attempt to cyclize. Can you generate a topology for
FXXXXL with a) -ter choosing none, b) -ter choosing anything else?
With Regards
