Hi, Yes indeed, as Matt was kind enough to point out, we do have the HC1 installed at station I911-3 of the MAX-II ring and you are welcome to make a rapid access application. One advantage of MAX-lab might be that our wiggler beam is more merciful to the crystals at room temperature than the

Dear colleagues, Sorry to present the stereo issue to the board again. Since my old SGI CRT monitor only has 75 HZ refresh rate, the flickering in stereo mode bothered me a lot. Recently, I want to update my old CRT to 120 HZ LCD. I have a Nvidia Quadro FX3800 in my workstation. I would like

1. No you cannot use your old stereo emitter. The 3D Vision Emitter is required for stereo on 120 Hz LCD monitors. You will also need new shutter glasses from Nvidia, but these some with the emitter. I'm not sure the reason, but I'd guess that the older emitter can't transmit the signal at the

Dave, thanks. There is an option for Zalman stereo in Coot. Could Zalman stereo also display properly in Pymol? Yu 2011/5/6 Dave Roberts drobe...@depauw.edu I'm very happy with Zalman passive stereo. No hardware requirements beyond Zalman monitor. Monitors cost $500ish for 21 and 700ish for

I think all major programs used by crystallographers use Zalman option. I know that coot and chimera do as does the version of pymol I have running (which is old). I don't know about other programs, but I don't know why not. Dave Sent from my iPhone On May 6, 2011, at 12:04 PM, zhang yu

[ccp4bb] Lyophilized protein sample (purchased)

2011-05-06 Thread REX PALMER
We have purchased a 5mg commercial sample of a protein we want to crystallize. On arrival it transpired that the sample had been lyophilized. Does anyone know if this is likely to give problems and if so what can/should be done about it?   Thanks in advance   Rex Palmer Birkbeck College

I think that's impossible to say. Some proteins lyophilize fine, some don't. Generally your chances are best if the protein is sturdy. Is also depends how it was lyophilized (any salts, buffer etc). Getting the protein in solution may be tricky; in my limited experience plain water works best

We recently had issues setting up a 3D projector and have tried lots of combinations of monitors, drivers, cards, glasses, etc. The answer seems to be that interchangeability is very complicated and you won't know unless you try it. For example, with the last version of the Nvidia driver I
