[gmx-users] question about topolbuild

[Hui Wen Ng]

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 below

 topolbuild -n modelname -dir path_to_interp. -ff forcefield

I have a ligand.mol2 and I typed in the command as below

topolbuild1_3/src/topolbuild -n ligand -ff oplsaa  -dir topolbuild1_3/dat/gromacs/

I got this error: Segmentation fault

Could anyone helpme with this please? Thanks a lot.

Best,
HW
