[gmx-users] Regarding calculation of Salt bridge between specific group of atoms

[bipin singh]

Dear all,

I want to calculate the salt bridge interaction between a particular
set of residues,
because I can not use index file with g_saltbr, so the next options
available are
g_dist and g_mindist. As stated in manual g_dist gives the  distance between the
center of mass of two groups of atom, while g_mindist gives us the minimum
distance between any pair of atom.
My doubt is that which distance(either given by g_dist or g_mindist)
corresponds to the salt bridge interaction distance
between two atoms.
