Dear Justin many thanks for your email and your comments. I found aminoacids.dat in the following pat
/apps/gromacs/4.0.5/share/gromacs/top I connect to imerial college via vpn. they have installed several gromacs versions. I only write module load mpi and then module load gromacs and then the gromacs commands become active. ------- the g_msd_mpi command worked and now I have msd.xvg file and I plotted it using gnuplot with this command: gnuplot "msd.xvg" u 1:2 w l now pls let me know how can I save this plot? I have written about that but I am confused. Thanks for your time Best regards Delara --- On Wed, 12/22/10, Justin A. Lemkul <jalem...@vt.edu> wrote: From: Justin A.

Hijacking an existing thread confuses the archive and will likely get your question ignored by anyone not interested in reading about Buckingham potentials. I have changed the subject line appropriately. See comments below. delara aghaie wrote: > Dear Justin > I hope all is well with you. I have faced a problem.

Certain input files are required by certain Gromacs tools. In all likelihood, you simply haven't set up your environment properly, but I'm not sure how that's possible. What version of Gromacs are you using? How was it installed? Are the Gromacs executables included in your $PATH, or do you have to find them manually in order to use them (i.e., do you run /path/to/gromacs/bin/grompp or just grompp)? Also note that there is no value in compiling the entire Gromacs suite with an MPI compiler. I've seen that cause weird behavior before, but I doubt it's necessarily related here. The only MPI-aware program is mdrun. -Justin > your help would be greatly appreciated/ > *Best regards* > *Delara* > * > * > > --- On *Wed, 12/22/10, Justin A.
