Dear colleagues,

Please be informed that the 1.3 release of the RELION software is now 
available for download. It's main new features are:

1) a movie-processing procedure for small particles (we'll show next 
week at the GRC how it helped to get 4.5 Angstrom resolution on a 170 
kDa membrane-protein complex)
2) a template-matching based automated particle picking algorithm 
(already used on several high-resolution structures in our lab)
3) a new GUI with image-displaying functionalities. Just click your way 
through the entire image processing pipeline: so no more "awk" commands 
to select particles or .csh scripts to group them! :-)

This release is a big step in the evolution of RELION from a stand-alone 
refinement program into a convenient pipeline for most of the 
single-particle analysis. As always: more details and download 
instructions are on the RELION wiki at 
http://www2.mrc-lmb.cam.ac.uk/relion. Please note we use the CCP-EM 
mailing list (http://www.jiscmail.ac.uk/CCPEM) as a forum for 
RELION-related questions, bug reports, etc.

Have fun,

PS: A special thanks to all those involved in beta-testing. Please 
re-install the 1.3 release if you have previously worked with a
