| VERSION 3.1 |
g_mindist computes the distance between one group and a number of other groups. Both the minimum distance and the number of contacts within a given distance are written to two separate output files.
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. This option is very slow.
Other programs that calculate distances are g_dist and g_bond.
