Chris This is, what I usually do, too. Still you need the parameters for your ligand from somewhere ;) Regards Maik Goette, Dipl. Biol. Max Planck Institute for Biophysical Chemistry Theoretical & computational biophysics department Am Fassberg 11 37077 Goettingen Germany Tel. : ++49 551 201 2

Hi, Contrary to Chris, I think it's easier/better to leave the .rtp database for building blocks of chains (and definitely advocate against bothering with the file for newbies). Small ligand topologies are better made seperately "by hand" and inserted in manner similar to the procedure in John Ker

2008-01-10 Thread Chris Neale
When actually building the topology I find it easiest to create the residues in the relevant .rtp and allow pdb2gmx to build the topology for you. However, all this does is correctly connect everything and put your parameters where they should be. All previous comments (in this thread and the h
