Dear VMD experts,

I have technical question about calculating salt bridges in VMD. When VMD
plots the distance between let's say GLU7 and ARG56 as a function of time,
what distance it actually is? Between what atoms of these residues? Or is
it distance between centers of mass of negative and positive charge?

Thank you,

Dawid Grabarek
