The representative structure of each cluster is the frame with the
lowest cumulative "distance" (in your case RMSD) to every other frame
in the cluster. A cluster representative is just that; it's supposed
to be representative of what that cluster looks like (although this
may not always be the case). I can see how comparing representative
structures to the average structure of the cluster could be
informative ('avgout', 'avgfmt'), but it's not clear to me what
insight you can gain from comparing representatives to the overall
average structure.
