Dear all, Version 2.7 of CCP4MG is now available for download from:
http://www.ccp4.ac.uk/MG/download/ The complete list of changes is give below. Best wishes, CCP4MG team. * OpenGL (graphics window use of hardware): Shadows. (Display->Lighting->Shadows check-box). Occlusion lighting effect (buried objects are darker than than exposed ones). Object outlines (edge detection). Shaders working on older (HD3000 series) ATI/AMD cards. Program runs again on Microsoft reference OpenGL 1.1. Fixes for some Windows startup problems. Slighty faster transparency. Text can have a background colour. Text can fade with fog. Speed improvements on Windows. Screenshots up to 8000x8000 pixels on most systems. * Status files: Portability improvements for status files. Fix saving data files in presentations/archives. Unicode filename fixes. * Symmetry: Contacts in "Crystal" symmetry method. Symmetry can be on/off for individual display objects; can ignore central symmetry mate. * User interface: Improvements to PISA interface. Speed up sequence viewer when there are many structures/chains. Clicking on an atom which is labelled from a previous click unlabels it. Atom selections can be given names. Restore the "run Coot" feature. * "Vibrations" module (normal modes): Clicking on a mode in "Vibrations" when another is already running will switched to the clicked one. Generally more expected behaviour in this GUI. Show theoretical b-values button labels plots much more informatively. * Picture wizards: Many picture wizards now draw something more sensible by default: broken ribbons are complete ribbons if no range for break is specified; multi-model CA trace works with one model. Wizards support "Crystal" and "View" objects. New way of generating complex scenes with electron density using new XML scene description + new picture wizards. Currently only in batch mode and undocumented. * Object drawing styles: Edges of ribbons can be coloured grey (colour will be user-specified in 2.7.1). User can specify degree of which loop-shortening effect. Fix drawing of some bonds, e.g. S-S > 2.2 angstroms. Ribbon representation of cyclic polypeptides wraps around on itself correctly. On-screen display of bond/dihedral angles in "Geometry" mode. Fixes for slice and mask density representations. Geoemtry labels behave better on black background. * Other: Symmetry colours fixed in "Render" module. Fix crash in "Geometry" module. Cope with multiple mtz files on command line. Work with CCP4 6.3.0 libraries and PISA. Install Windows VC++ redistributable package on Windows to fix compatibility with some versions of Windows.
