Dear All, The CCP4MG team would like to announce version 2.8.0 of the program (the Christmas 2013 release).
The program may be downloaded from http://www.ccp4.ac.uk/MG/download/ Highlights of this release include: - Reworked picture wizards and default program parameters to give more complete and accurate scenes automatically. - Ability to handle much larger electron density maps (including EM maps with new colouring schemes). - Gesamt option for structure superposition. - Worm representation scaled by B-factor or NMR variability. - Rapid calculation and display of biomolecules (from BIOMT cards in PDB files). - Faster drawing speed. - Many improvements to thermal ellipsoids, "circles" and "perfect sphere" styles. - Atom selections can be saved as new file. The complete list of new features/fixes can be seen on the download page and at the end of this message. Happy Christmas, CCP4MG Team. User interface and related * Radical revamp of picture wizards to give more complete and accurate scenes automatically. * Calculate and display quickly biomolecules specified in PDB files. * Clicking on Peptide->A in selection browser only selects peptide now, not whole A chain. * Sequences can be saved to text files for loading into external programs. * Scale bar option on main display. * Screen origin displayed in status bar. * Drag/drop of files sets file browser default directory to where file was dragged from. * Allow saving of PISA assemblies and general bug fixes in PISA interface. * Can now save atoms of an individual display object selection to PDB file. * Gesamt option for structure superposition. * Fix render on Windows when not installed on C: drive or user drive is not on same drive as Program Files. * Rib file no longer saved when batch rendering. * Superpose and PISA now behave properly together. * Fix bug with S-S bridges when doing superposition or other structure movement. * Allow user to specify minimum length of alpha helices. * Allow use of alternate locations in atom pickers and hence vectors. * Fog propery can vary between scenes in movies. Electron Density * Handle electron density maps up to about 1000 angstroms cubed. * Handle electron-microscopy maps properly by not attempted to recalculate with symmetry. Colour by radius option for these maps. * Allow loading of gzipped map files. * Difference maps are red/green by default. * Can specify electron density contour level, etc. to 4 decimal places. * Can now download structure factors and calculate map. Chemistry * Many more monomer types correctly identified as peptide, solute, saccharides, etc. * Helix generation tool produces better geometries and now has various beta sheets. * More chemically realistic distances used to calculate H-bonds and metal contacts. Display * Drawing speed 2x faster. * Improve quality of "Circles" style, especially with screenshots. * Improve quality of thermal ellipsoids. * Worms scaled by b-factor and NMR mobility. * Custom clip planes. * "Clip-capping" for "Perfect spheres" and "Spheres". * Ambient occlusion fixes for spheres. * Perfect spheres are now lit by all lights. * Perfect spheres are now clipped much better. * HBonds and Contacts have separate global styles. * Text labels can be obscured by nearer objects. * Lighting speedups for older nVidia cards. General * Tutorials and other documentation updates. * Speed up program when there are lots of display objects. * Fixes for compatibility with various compilers. * Use CCP4 version 6.4 libraries. * Major overhaul of build system for future compatibility with CCP4 suite.
