Dear All,

I am following up on an earlier post (to which nobody replied except an
unhelpful comment about asking Siri) to ask whether anybody have a script
for calculating the angular distribution function of molecules in a VMD
trajectory?

Angular distribution functions are used to map the average angular
orientation of a molecule (e.g. water) relative to a planar surface as a
function of spatial position. They are used in papers such as

Many thanks!
