I think I've fixed the problem for adding RNA nucleotides. One of
the internal Coot functions wasn't fully updated with the new residue
names (i.e A and C instead of Ar and Cr). Try out 0.7-pre-1 revision
3628 when it gets packaged for OS X and let me know if it works. Paul,
should I back-port the fix to the 0.6.2 branch? It's no extra effort,
but I wasn't sure if you wanted to completely freeze that branch.
Also, as long as the subject of RNA has come up, I wanted to throw
in a shameless plug for RCrane (http://pylelab.org/software/#rcrane).
It's a Coot plugin that partially automates the building of RNA in maps
of up to ~4 A resolution. I just released a new version of it last week
(version 0.7), and I'd love to hear any feedback on it.

Hi,
Yet another reply to one of my own posts! Some more information though.
I've now hacked the coot.info in fink and compiled the latest pre-release so
I'm now running:
0.7-pre-1 (revision 3627) [with guile 1.8.8 embedded] [with python 2.7.2
embedded]
The library was still the old version so I replaced /sw64/share/coot/lib with
the directory from
coot-0.7-pre-1-revision-3627-binary-Linux-x86_64-centos-5-python-gtk2.tar.gz
If I build DNA using the ideal DNA/RNA builder I can add nucleotides on to
either end no problem. If I build RNA I get:
ERROR:: nucleotide_to_nucleotide() unassigned type mol_base_is_pyrimidine: 1
mol_base_is_purine: 0 std_base_is_pyrimidine: -1 std_base_is_purine: -1
mol_res_name: U std_base_name: A
Also if I mutate to Thymine using simple mutate C7 is missing (as reported a
few days ago).
Hopefully that'll help finding out what the problem is...
