Hey, For the average distance matrix, you can use g_rmsdist. Cheers, Tsjerk On Mon, Apr 15, 2013 at 6:19 PM, Justin Lemkul wrote: > > > On 4/15/13 12:08 PM, Steven Neumann wrote: > >> And last question: >> >> Are these minimum distances averaged over the simulation time? Cannot find >> any e

And last question: Are these minimum distances averaged over the simulation time? Cannot find any equation the way it is calculated... in Manual its written: This minimum distance between two residues Ai and Aj is defined as the smallest distance between any pair of atoms (i 2 Ai, j 2 Aj ). The o
