Yes, confirming tests made here by InSuk Joung.

According to the supplementary material from Banas10, you should do this:
source $AMBERHOME/dat/leap/cmd/leaprc.ff99bsc0
loadamberprep all_nuc94_ol_bsc0.in
loadamberparams frcmod.ol.dat
The files for the last two lines are in amber11/dat/leap/ff99bsc0chiOL.
Setups created this way should then be tested against leaprc.ff10.
I'm really, really hoping that tec will chime in, since I think(?) he has
access to the "real" prmtops used for the tetraloop simulations reported
in the Banas10 paper. In addition, we want to be sure that we are really
doing the "right thing" with DNA as well. (A DNA setup with ff10 should be
identical to one from ff99bsc0.)
...thanks...dac
