<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Hi all,<br><br>I'm using AMBER99p force field in GROMACS. In the AMBER forcefield for some dihedrals, there are several values, in which n values are different. <br>As an example, for C3-C3-N-C, I have<br>C3-C3-N-C .50 180.0 -4<br>C3-C3-N-C .15 180.0 -3<br>C3-C3-N-C .53 0.0 1<br><br>For the version 4, is there a convenient way to use these multiple
dihedrals?<br>Thanks,<br>Amin<br><br></td></tr></table><br>
