[gmx-users] dynamic indexing

[Christoph Freudenberger]

hi there,

I'd like to do some sort of "dynamic indexing" in an analysis tool.

If the tool finds an atom to be within a given distance range
from another atom it should get the atom numbers of all the atoms
with the same resid to perform further calculations with them.
What I need is something like the "same resid as..." feature
in vmd.

I could write a loop that checks the resid for each atom in the
system, but that would be rather expensive.

Is there a way to do that smarter?
