Hi, We've put out a "release candidate" for download (version 1.2056). We're hoping people will download it and try it and report any problems they find before we make a production release version in early January. The production release candidate will be functionally identical to the production release, except that we will fix any bugs reported between then and now. There are some new features in the 1.2056 release, and if you are interested in those you should really try it out so that if you find any problems they will be fixed in the production release. Here's a synopsis of the major new features since the 1.2038 release: NEW TOOLS: Surface Area/Volume (Utilities) - calculate surface areas and Voronoi volumes with the StrucTools server at http://molbio.info.nih.gov/structbio/basic.html TOOL CHANGES: Movie - support added for MMTK/NetCDF trajectory format - RMSD maps containing all-by-all comparisons among specified frames can be calculated (for all atoms or selected atoms) Volume Viewer - support added for APBS electrostatic potential format and TOM toolbox EM density map format sequence panel (opened from Model Panel) - secondary structure shown with color NEW COMMANDS: matrixget - write the current transformation matrices to a file matrixset - read and apply the transformation matrices from a file mmaker (matchmaker) - command implementation of MatchMaker; generates a sequence alignment for two structures and then superimposes the structures accordingly BUGS FIXED: large structures without HELIX/SHEET records now much faster to open (fixed bug in secondary-structure computation) non-default ribbon scalings from pre-1.2038 versions no longer cause bombing on startup (1.2038 would die at startup for such) Eric Pettersen UCSF Computer Graphics Lab pett@cgl.ucsf.edu
