[gmx-users] RDF around cylinder

[Steven Neumann]

Dear Gmx Users,

I have my carbon nanotube (lenght z axis) with proteins attached to it. I
wish to collect RDF of given type of amino acids away from the surface in
two dimensions (xy). Z axis does not interest me. That would make a circle
then. My question: how to make a specific index group of this circle? Any
ideas appreciated.

Steven
