You can do all the preparation steps on your own machine. Alternatively, you
can always make a copy of the force field directory (and its entire contents) in
the working directory and make any changes there. pdb2gmx will detect the
directory in the working directory and use its files to generate the topology.
Doing so circumvents any permission issues.
