3 g_dist - calculates the distances between the centers of mass of two groups
10 .BI "-n" " index.ndx "

21 g_dist can calculate the distance between the centers of mass of two
22 groups of atoms as a function of time. The total distance and its
23 x, y and z components are plotted.
28 is set, print all the atoms in group 2 that are
29 closer than a certain distance to the center of mass of group 1.
36 the number of contacts
37 of all atoms in group 2 that are closer than a certain distance
38 to the center of mass of group 1 are plotted as a function of the time
39 that the contact was continously present.
42 Other programs that calculate distances are
