[gmx-users] Re: regarding NA+

[Tsjerk Wassenaar]

Hi Vijay,

The name in the structure file (taken from the genion -pname option)
does not relate to your error. If it does not match the name in the
topology, it will merely lead to a warning.

Now, in an attempt to resolve your issue, I've browsed through your
recent mails, but there's no proper reference or description of your
problem whatsoever. Besides that, the way you have written it makes it
hard to read, as Mark pointed out earlier. I recall that these are the
two reasons I've refrained from replying in the first place (proving
Mark's point).

But, if you could give us a proper account of your problem, we might
be able to solve it (or you might be able to solve it yourself, since
dealing with and presenting your problem in a structured way may make
it clearer for you too). So...

1. What force field did you use (I believe it was GROMOS96 34a1, in
which case atom name and molecule name are both NA+)?
2. What do the last 30 lines of the topology file say?
3. What's in your .mdp file?
4. What is grompp complaining about (give the output, in particular
the lines about warnings/errors)?

By the way, did you read the Manual/Wiki/FAQ/Mailing-list to see if
your problem was addressed there?
