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.
