[gmx-users] Help with make_ndx and

[Giorgos Karvounis]

Hi,

My name is Giorgos and i am a new Gromacs user. My problem is that i
need to extract and follow the coordinates of a specific aton in a
protein (e.g C1) or a group (e.g. carbonyl) but i'm not comfortable with
the index.ndx or make_ndx command... Any help will highly appreciated!

thanks

Giorgos
