Create Molecular Dynamics starting configuration

Little script (relying on GROMACS) to create initial molecular dynamics (MD) boxes. The example attached is for a box of a fullerene derivative, PTEG-1, but the script can be adapted to anything else. See the "a_new_fullerene_box.sh" for some instructions. There is plenty of room for improving the script.The MD files (i.e., single molecule coordinates and topology) for the fullerene derivative are from:Enhancing doping efficiency by improving host-dopant miscibility for fullerene-based n-type thermoelectricsL.
