Hi all,<br>I'm sorry for the dumb question but I need to put harmonic restraints on my peptide and I cannot find the right command. So, looking on the how tos link in the gromacs website I understand that I need to add to my topology file a posre.itp file with the section [ distance_restraints ] specified with type 6. However I cannot find the command to generate this .itp . On the contrary, for positions restraints there is the genpr command that does it, so I'm looking for the equivalent for the distance restrains. Can anyone help? Btw, I'm using GROMACS 3.3.1,<br>
Thanks<br>Francesca<br>
