Dear Hadi,<br>
<br>
You also forgot to define "better". What do you want to learn from that
peptide? Do you need all hydrogens for that? Or could you do without?
Also consider that the generality of the question phrased does usually
not trigger people in a way desired for reply. It sounds a bit like
"I've got some homework, but would like you to do it for me". Study the
manual and papers on MD, in particular of small peptides and force
fields. Now there's a bit of homework ;)<br>
<br>
Cheers,<br>

<br><br>General force fields are parameterized to be reasonable over a range of<br>systems. The overview of force fields in the GROMACS manual is good, and<br>you should refer to the papers that describe them for more detail.
