It is recommended to make the box in \&the input file at least as big as the coordinates + \&van der Waals radius. \&If the optional trajectory file is given, conformations are not \&generated, but read from this file and translated appropriately to \&build the grid. .SH FILES .BI "\-f" " conf.gro" .B Input Structure file: gro g96 pdb tpr etc. .BI "\-o" " out.gro" .B Output Structure file: gro g96 pdb etc. .BI "\-trj" " traj.xtc" .B Input, Opt.
