[gmx-developers] Charmm27 and RNA gives No default Angle types errors

[Daniel Larsson]

Hi all,

Is the nucleic acid support still under development? I tried to process a small RNA molecule with the latest head version of Gromacs. pdb2gmx is fine, but grompp chokes when building the topology since it can not find any angle parameters and gives one of these errors for each angle:

ERROR 1 [file topol.top, line 479]:
  No default Angle types

Regards,
Daniel
