Dear Gromacs Users,


I need to extract all possible distances between any two atom pairs of a small hexa- to dodecamer from a trajectory. The same is necessary for all dihedral angles of this protein. Now I wonder if this is possible without defining all of them manually in the ndx file and call g_dist for each of them ? Is there a short answer on that ? Maybe I missed the answer to that question in the forum ?!


That level of detail might just require some iterative calls to g_dist and g_angle, unfortunately. Scripts are your friend, here. Also, g_mdmat might be useful, but it plots minimum distances between *residue* pairs, not atom pairs. Much more convenient than repeated calls to g_dist, however :)
