[gmx-users] how to freeze an arbitrary set of atoms

[Irem Altan]

Hi,

I would like to freeze a subset of protein atoms in my system. Since I don’t want to freeze them all, I can’t really do the following:

freezegrps	= Protein-H
freezedim	= Y Y Y

How can I define a custom set, e.g. atom indices {400,1200,234} etc.?

Best,
Irem
