402	nonstandard RNA residues cause cartoon (ribbon) problems	Elaine Meng	Conrad Huang	"It looks like the nonstandard nucleic acid residues in a tRNA (for example, 1ehz) are not completely recognized. I say ""not completely"" because they are still treated as part of the polymer chain, but the cartoon (ribbon) is thin like peptide coil instead of having the nucleic-acid ribbon dimensions. The ribbon plane of the residue right after each thin segment is messed up, similar to the protein issue reported as #333. Looks like these nonstandard residues do have the standard ribose-phosphate backbone, with both the C5' path atom and C1' orientation atom, and are specified by command-line ""nucleic""... they just need to be recognized correctly by the ribbon code, as far as I can tell. There are many modified bases in ribosomal and tRNA, so I don't expect this to be rare.

Reassign if I got the wrong person.  :-)"	defect	closed	major		Depiction		fixed		Eric Pettersen Tom Goddard				all	ChimeraX
