Thank you Maik.
The AMBER ports are some I'm testing, sure.
BTW, I can't get it ready if I solvate the model. Everything goes fine
until grompp complains:
$> grompp -v -f em -c watered -o em -p nucT
(...)
- -------------------------------------------------------
Program grompp, VERSION 3.3
Source code file: toppush.c, line: 1108
Fatal error:
[ file "/usr/local/gromacs/share/gromacs/top/spc.itp", line 41 ]:
Atom index (1) in settles out of bounds (1-0)
- -------------------------------------------------------
Any clues of what may be wrong?
order of bits in the topology file. chpater 5
If I don't solvate the model and remove the include line in the top file
for "sol.itp" the problem disappears...
Thank you,
Miguel

Take the Amber-Port:
http://folding.stanford.edu/ffamber/
http://www.gromacs.org/topologies/uploaded_force_fields/ffamber_v1.0-doc.tar.gz
But beware of renaming atoms and residues before use. If you don't
pdb2gmx will inform you about problems.

Dear all,
This is a question from someone just taking some timid steps in this
field. I'd like to know what force field, among those available in
Gromacs (v. 3.3) would you consider "better" for models containing
nucleic acids. As I understand this may be kind of a matter of taste and
could open a somehow sterile discussion, I would suggest you send your
opinion/arguments to my address. I would then compile a summary of the
answers and post it later.
Thanking you in advance for your kindness.
Cheers,
Miguel
