[gmx-users] Delete Groups from gro file

[Gselman, Larissa]

Hallo All,

I have a big gro file with 10 different groups. For my simulation, I only need one (Group 6) of them in a new gro file.

So, how can I make this new gro file?

I made an index file with this command:

gmx_mpi make_ndx -f membrane.gro -o membrane.ndx

and selected my group with „keep 6“

Is there a command to create a new gro file only containing this group 6?

Thank you very much for your help!

Kind Regards,
Larissa
