[gmx-users] converting Desmond trajectories to Gromacs
Dear Sir/Madam I am running simulations on a membrane protein using Desmond and I want to calculate area per lipid for the entire trajectory. I can convert the trajectories to those of Gromacs using VMD. What else do I need in order to calculate area per lipid using Gromacs?

The area per lipid is not a trivial quantity to calculate when there's a protein involved, and there is no Gromacs tool that will do it. We created a program a few years ago that does, but note that you cannot analyze a trajectory, only a single coordinate file (.gro or .pdb). The current workaround is to dump out a series of coordinate files and loop over all of them in a shell script. Note that, depending on how many frames you have in your trajectory, this may take quite a while - APL calculations typically take on the order of 2-5 minutes (per frame), depending on how large the system is. http://www.bevanlab.biochem.vt.edu/GridMAT-MD/ -Justin -- Justin A.
