How do I visualize a group made with gmx make_ndx?

GROMACS version: 2020.3
GROMACS modification: No
How do I look at the atoms selected with gmx make_ndx in a program like Chimera? I want to make sure I’ve selected the right atoms. Thanks in advance for your help with this! It is greatly appreciated.

Provide index file to trjconv tool to dump desired coordinates

If you don’t have a trajectory yet you can also do it with editconf or select.
