ehex command help

Hello,
While using the 'ehex command’ (shown below) and I get the error message: “Unknown fix style (…/modify.cpp:815)”

region source block EDGE EDGE EDGE EDGE EDGE EDGE

fix 1 gn ehex 1 100.0 region source

Then, I tried to run the example ‘in.lj.ehex’ from the examples dir and I get the following error message:
“Unknown pair style (…/force.cpp:240)”

Does lammps-17Nov16 installation come with the ehex package and pair_style lj/sf cutoff?

Thanks,
Daipayan

ehex is not included in the default package. You have to compile with the RIGID package in the lammps directory you downloaded.
