I am currently working with an RNA duplex and following the NMR refinement tutorial online and encountered an error when trying to convert my 5col.sugar file to the rst.sugar file using makeANG_RST -pdb gcg_b.amb.pdb -con 5col.sugar -lib $AMBERHOME/src/nmr_aux/prepare_input/tordef.lib > RST.sugar
Here is the error: ERROR: 17 URI PPA: No definition for URI PPA in torsion library. Skipping...
I am using the following pseudorotation phase angles for all my nucleotides:
2 ADE PPA 0.0 30.0\
4 CYT PPA 0.0 30.0\
Should I be using a different library for working with RNA and if so what is that called?
Thanks,
Charlie
