I'm having troubles with grompp.
Building .gro and .top files from a .pdb file of a 7 residue peptide
(61 atoms in uaff) results in a system with 5137 atoms in the gro file
and a .top file with 1 protein (61 atoms) and 1692 solvent (5076
atoms). When I ran grompp it fatal erred stating that the "number of
coordinates in the coordinate file (5137 atoms) does not match topology
My .mdp file had the default
cpp = /lib/cpp
so I ran the command; 'which cpp', which returned /usr/bin/cpp
I changed the .mdp to
cpp = /usr/bin/cpp
and I get the same error.
If I run grompp with the -pp option the processed top file returned is
Could this have something to do with the
include = -I../top
in the preprocessing section of the .mdp file? It would seem to be the
only thing left.
This is a linux box running Fedora Core 5. No significant modifications
were made during the install of either the OS or GROMACS.
