Dear All, The CCP4MG team would like to announce the latest release (version 2.5.1) of the program. This is largely a performance and stability improvement release. A fuller list of changes is given below. The program can be downloaded from:
http://www.ccp4.ac.uk/MG/download/ Best wishes, CCP4MG * Major speed in improvements from rewriting OpenGL drawing to use Vertex Arrays and Vertex Buffer Objects * Fix several memory leaks, especially serious ones when saving movie frames and deleting structures. * Fix translation problem when generating assemblies in PISA interface. * The Linux binary is now built on CentOS 5 for better compatibilty with more Linux distributions. A build parameter was also changed to increase portability and stability. * Multiple lights now work when OpenGL shaders active. * Better transparency of surfaces. * Flat colour option inside surface with shiny outside with OpenGL shaders. * Fix problem with clipping of maps after transformation has been applied. * New drawing style "Circles". * Small utility to generate idealized alpha, pi and 3-10 helices. * Fix problem with some hydrogen-bonds not being dashed lines when they should. * Approximate normal modes calculation and visualization. * Fix problems with bits of file dialog still being visible after closing. * Support for filenames/directories with non-ASCII names. * Fix problems with lighting in Render module. * Selection improvements: much better performance with large structures, use SITE specification in pdb files. * Improvements in identifying lipids. * Colour blend goes form blue to red as chain goes N to C. * Movie preferences simplified. * Fix problem with R3/H3 symmetry from pdb files. * Fix the "Error with fixed model" problem when restoring status in Superpose. * Fix loading of animation from file with multiple models. * 2FOFCWT, PH2FOFCWT columns selected by default, if present, when loading mtz file. * Fix problem with long file names in sequence viewer. * Visual improvement in the "Axes" style of thermal ellipsoids. Fix loading of some clustalw files into sequence viewer. * Experimental visualization of results of ProSMART calculations. Colour by ProSMART score and superpose using ProSMART transformation matrices implemented. * Display table docked by default. * Built-in movie player for Linux. * Some additional options in picture definition file View stanza: scale = 'auto' (zoom to show whole molecule), scale = '25 ang' (zoom to have 25 angstroms from screen top to bottom); add option to orient view along smallest principal component e.g. orientation = {'molData':'toxd','selection':'// /45-46'}
