Dear Mark
Thank you for your reply
Do you mean I can ignore the charge?
Only if you want an expensive random number generator.
If the topology is broken, what should I do?
I already answered this. Appearing not to read the detailed reply that
someone gave up their time to write, is a great way to avoid getting
yourself any help in the future. :-)
The number isn't integer, So how many counterions I should add?
Never mind about ions, probably your topology is broken before you got
started :-) Check your capping groups. If you used pdb2gmx, have a look
at the right hand (comment) column of the atom listing, where it shows
the cumulative charge. This will help you find the residue where things
start getting non-integral.
