Dear collegues, a while ago, there was a discussion in the board on the term apo-structure as a way to descibe a native, free, or unbound protein (no ligands). I think the conclusion was that an apo-form is a halo enzyme lacking a cofactor and should not be used as a substitute for "unbound". We

Hi Christine, as far as I know, it does not work at all with Geforce cards. The Nvidia drivers do not support windowed quad buffered GL, which you need for coot/pymol. It does not matter whether you use Windows or Linux. But this is based on my personal experience from around Oct. 2016. Maybe

Hi Matt, I guess you are talking about hardware. For a year or so, this should have become quite cheap. A recent Nvidia Geforce card, a 120 Hz 3D Monitor and a 3D vision kit should do the trick. However, personally I only have experiences with the "professional" NVidia quadro grafics card series.
