Hi All,<br> I am a novice in gromacs. I want to study sugar/membrane interaction and I want to use gromos96 45a3 ff. At first I am planning to simulate dopc bilayer + water. I downloaded the pdb file of dopc from the site <a href="http://www.bioinf.uni-sb.de/RB/">http://www.bioinf.uni-sb.de/RB/</a> . Then I typed pdb2gmx_d -f dopc.pdb and choose gromos96 45a3 force field. But I got the error "Residue 'OLE' not found in residue topology database". How can I fix the error?<br>
Thanks<br>Chanchal<br><br>
