       g_mindist - calculates the minimum distance between two groups

       VERSION 4.6.5

        g_mindist computes the distance between one group and a number of other groups. Both  the
       minimum  distance (between any pair of atoms from the respective groups) and the number of
       contacts within a given distance are written to  two  separate  output  files.   With  the
       -group option a contact of an atom in another group with multiple atoms in the first group
       is counted as one contact instead of as multiple contacts.  With  -or,  minimum  distances
       to  each  residue  in  the first group are determined and plotted as a function of residue

       With option  -pi the minimum distance of a group to its periodic image is plotted. This is
       useful for checking if a protein has seen its periodic image during a simulation. Only one
       shift in each direction is considered, giving a total of 26 shifts.   It  also  plots  the
       maximum distance within the group and the lengths of the three box vectors.

       Other programs that calculate distances are  g_dist and  g_bond.
