[gmx-users] adding iodine

Magnus,

On first guess, it looks like you left out 

#include ions.itp  ... from your topol.top file.

Good luck,

Matt

Subject: [gmx-users] adding iodine

Hi all!

I'm experiencing problems adding iodine to FF GROMOS96. What I've done is
add the following to the force field (in ions.itp):

[molecule name]
;molname    nrexcl
I-          1

[atoms]
; id    at type    res nr    residu name    at name    cg nr  charge   mass
  1     I-          1         I-            I           1      -1  126.9045


And the error message given by pdb2gmx is:
'Atom type I not found in atom type database'

What am I missing?
