Mark - Original Message - From: Gavin Melaugh Date: Tuesday, September 28, 2010 19:04 Subject: [gmx-users] topology file for two molecules To: Discussion list for GROMACS users Hi all I want to run a simulation of one tert-pentane molecule inside one organic cage molecule. I have the topology files for both molecules but obviously I only need one .top file as the input for grompp. What is the most convenient way of having both topologies in one file?

Re: [gmx-users] topology file for two molecules
Hi Mark. I have looked this up, but I am a little uncertain. Does one of the topologies have to be included within the other as an .itp file. If so do I only define the [defaults directive] in the .top file i.e. I take it I don't include this directive in the .itp file as well.

Look up the include file mechanism on the webpage.
