If using Linux, definitely a dedicated NVidia - their drivers are the best supported by far. There are also some issues right now with the drivers for some of the integrated Intel graphics cards, a bug with handling OpenGL applications which prevents O, Coot, and PyMOL from working properly, am

NVIDIA NVS 3100M is an entry level card that mostly is designed with 'business applications' in mind - meaning that its rendering/polygon/3D engine is relatively weak compared to an average or even low-end modern desktop graphics cards. Nevertheless it is definitely a step up from an integrated car

Dear all, I wanted to know which type of graphics card is more suitable for a notebook which is going to be used for structural biology. Integrated or dedicated? ATI or NVIDIA? At the moment I have to choose between an integrated Intel HD Graphics or a dedicated NVIDIA NVS 3100M Graphics. Any s

Re: [ccp4bb] Effect of NCS on estimate of data:parameter ratio

2010-09-19 Thread Ian Tickle
Hi Florian, Tight NCS restraints or NCS constraints (they are essentially the same thing in effect if not in implementation) both reduce the effective parameter count on a 1-for-1 basis. Restraints should not be considered as being added to the pool of X-ray observations in the calculation of the
