[Xplor-nih] rna database potential refinement

[Gokul Ramaswami]

Hello Xplor users,

I am trying to refine an rna molecule using the rama and orie database 
potentials.  The problem is during the final minimization I get an 
error message stating that the gradient may be incorrect and the 
program terminates.  If I take out these 2 potentials, then the 
minimization occurs without error, but the structure has poor base 
stacking.  Any help would be greatly appreciated.

Thanks,

Gokul
