If you have not renamed the force filed files the entry in FF.dat should look like this:</div><div>ffcharmm27 CHARMM 27 all-atom force field</div><div>and don't forget to increase the number of the first line in the file either!</div><div><br></div><div>You could also try to run pdb2gmx with the flag -ff ffcharmm27 and see if that works (instead of selecting it interactively from FF.dat). Also take a look in the pdb2gmx output and see if any of the ffcharmm27 parameter files (I think ffcharmm27.rtp should be the first one read by pdb2gmx) are read.</div><div><br></div><div>I did the gromacs installation myself yesterday and I got it to work.</div><div><br></div><div>Regards,</div><div>Pär</div><div><br></div></body></html>
