Dear all,
Version 2.7.2 of CCP4MG is now available for download from:
http://www.ccp4.ac.uk/MG/download/
This version fixes two critical problems on Windows (failure to create
movies and complete failure to work at all with many Intel graphics
chips) and one critical problem on Linux (crash/hang at program start
with new nVidia graphics cards).
The complete list of changes is give below.
Best wishes,
CCP4MG team.
OpenGL/ Graphics Drivers
* Disable use of Vertex Arrays on all Intel Graphics chips on Windows
for now, but allow user to override this behaviour. Should now work on
all Windows machines, if not optimally.
* Make sure shadows are smooth when doing screenshot.
* Fix dark line styles when shadows are on.
* Shadows work with software Mesa (gallium/llvmpipe, Mesa 9.0 at least).
* Shaders/shadows, etc. work with some Intel graphics chips.
* Shader work with older NVIDIA shader version (1.20).
* Fix reversed z-buffer with screenshots on Windows/Intel.
* Fix hang/crash at at start-up with new nVidia chips on Linux.
* Fix dashed lines in non-VBO/VA case (e.g. MS OpenGL 1.1).
* Fix line colours in non-VBO/VA case (e.g. MS OpenGL 1.1).
* Fix symmetry for lines in non-VBO/VA case (e.g. MS OpenGL 1.1).
* EXPERIMENTAL: "Perfect spheres" style. "Ray-traced" spheres in
graphics window. Not antialiased however, so screenshot with 2X/4X size
recommended. Currently do nothing in "Render".
User Interface
* Fix critical bug creating movies on Windows.
* Restore from XML works on Windows.
* Fix loading of XML status files with selections with single quotes,
e.g. C5' .
* Fix "Apply all" to Annotation fonts.
* Sequence viewer option for "traffic light" or Consurf style colouring.
* Two new site+(broken)ribbons wizards which colour by molecule
instead of chain.
* Change back/forward to undo/redo.
* Fix undo/redo by always forcing reload of data files.
* Add download coordinates and screenshot to default toolbar buttons.
* Only draw half a bond if drawing external to another bond scheme
(i.e. not work/ribbon).
* Selection browser: Allow simple exclusion of CA when group==side
(exclude=alpha).
General
* Fix R32 symmetry generation from maps.
* Allow shorter CN bond.
* Symmetry off by default when an MTZ is loaded.
* Fixes for running Coot/refmac from CCP4MG.
Other
* Fixes for compatibility with CCP4 build systems (no user impact,
currently).
