[COOT] New Coot plugin for RNA building

[Kevin Keating]

    I've just released a new Coot plugin to help with building RNA 
structure, so I wanted to make a quick announcement to the mailing list 
for any interested RNA crystallographers.  The plugin, named RCrane, is 
free for use and can be downloaded from 
http://www.pylelab.org/software/index.html#rcrane.  There are also 
several screenshots on that site for anybody who's curious.
    RCrane helps with placing phosphates and bases into electron 
density, and then automatically determines coordinates for the remainder 
of the backbone.  It's designed for use in maps of up to ~4 A 
resolution, and requires a very recent nightly build of Coot 
(downloadable from 
http://lmb.bioch.ox.ac.uk/coot/devel/build-info.html).  The plugin has 
been tested under Windows and Linux.  It should work under OS X if you 
have a recent enough build of Coot, although I haven't done any testing 
there yet.
    For anybody who tries out the plugin: feel free to send me any bug 
reports or suggestions and I'll try to incorporate them into future 
versions.

    Thanks,
    Kevin
