Hey everyone, <br>I have a .pdb file that I need to convert to .gmx. The tricky thing is that the protein has a lipid bound to the N-terminus, which pdb2gmx doesn't recognize. The lipid is a myristic acid residue (14:0), and I haven't been able to find it in any database. What would be the most straightforward way to get pdb2gmx to recognize this structure? I plan on using multiple monomers in the future, so I'd rather not manually alter the .top file. I've been looking at modifying the .rtp file to include this residue, but then I'm wondering how to parameterize it. If anyone has any suggestions aobut any of this, I'd be really happy to hear it.<br>
<br>Thanks,<br>Gard<br>
