[gmx-users] How to convert coarse-grained to fine-grained

[Kieu Thu Nguyen]

Dear All,

I convert cg to fg representation by command lines

 g_fg2cg -pcg cg.top -pfg fg.top -c cg.gro -n 1 -o fg.grog_fg2cg -pcg
cg.top -pfg fg.top -c cg.xtc -n 1 -o cg2fg.xtc

But there is a notice "command not found" in the terminal.
I see this command used in Gromacs v3.3.1
Does it not run in Gromacs v4.5 ?

Any advice is welcome.
Thanks All !
KT
