This directory contains inputs, settings and a reference file for a 
fast-folding mutant of the villin headpiece. To use this mutant we need
to add a residue to the force field. The easiest way to do this is to copy
the entire amber99sb-ildn.ff directory 
(e.g. from /usr/local/share/gromacs/share) into your current working directory.
Then copy the file residuetypes.dat into the same place, and finally move
the norleucine.rtp file into the force field subdirectory.
