Dear all, I am trying to make figures of a peptide nucleic acid, that is, a molecule with protein-like backbone but nucleic acid-like side chain, meaning nucleobases. I cannot get Pymol to recognize the nucleobase rings as rings fo the cartoon_ring_mode, likely due to a rather unusual nomenclature. I copy a representative segment below. I tried changing the residue names to G and C, but still, no planar rings. So, what does pymol recognize as a ring, how must I rename the atoms/residues to get the ring representation? Is it a names problem or rather due to the absence of phophates and riboses? Any clever fix?
Thanks a lot, Jose Antonio Cuesta-Seijo.
