We have been running a DNA 18-mer and also a RNA tetranucleotide r(GACC)
with h-mass repartitioning on the solute only and on everything. From
initial analysis, conformational distributions appear fairly identical for
the r(GACC), however we still need to look at kinetics, water properties
(viscosity should be higher), etc. When Christina, Ros and I get it
further analyzed, I'll summarize to the dev list...

Ros/Christina, maybe we should fire up some more as per above. --tom
