[gmx-users] location of aminoacids.dat

[Justin A. Lemkul]

First, please start a new thread if you are asking a new question.  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.

That doesn't matter.  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.
