Information theory characterization and visualization of RNA secondary structure using Boltzmann ensemble finds a small number of most informative base pairs (MIBPs) and their conflicting base pairs (if any) controls three levels of structure.

LinearPartition shold do the probablilities part in near linear time.
They have a web server (beta).

Combined should be a fast way to get Most Informative Base Pairs (MIBPs) and their Conflicting Base Pairs so one can concentrate efforts on mutations that really matter.
