 Dear gmxusers,
 I have a question about using topolbuild to generate
 topology for my ligand (intend to use OPLS AA forcefield).
 However, I am facing a problem in using the command, which
 according to the README text, requires the basic input as
  topolbuild -n modelname -dir path_to_interp. -ff
 I have a ligand.mol2 and I typed in the command as below
 topolbuild1_3/src/topolbuild -n ligand -ff oplsaa  -dir
 I got this error: Segmentation fault
 Could anyone helpme with this please? Thanks a lot.
