CCP4bb navigationCCP4bb <-- 1999 <-- November 1999 <-- 30 November 1999Subject: Re: Popularity of Stereo graphics in crystallography From: "Latchem, MJ (Mike)" Mike {- dot -} Latchem {- at -} DIAMOND {- dot -} AC {- dot -} UK Date: 2007-06-21 I have found stereo essential for building low resolution structures where data beyond 3.3A is not available, I must also say that I have found it unnecessary for any structures which there is data (with decent phases) to 3A and beyond. The question is, is it worth spending a substantial amount of money for that one project out of 50 (for example) which will need a stereo workstation to build? My gut instinct would be yes - but only if you can.

You don't really need it and it's not worth the expense/hassle to set up. In my opinion it's just something to impress visitors! Dave ------------------------------- Dr. David M.

So I guess it's worth the pain of getting the stereo hardware to play nice with the OS and specialized applications. We put the cheapest stereo-ready cards available at the time(Quadro 980XGL) in our Linux workstations, along with NuVision 60GX glasses, and none of the workstations cost more than $2000 to build. If you don't need stereo, clearly almost any reasonable PC will do. Even the lowliest of Nvidia or ATI graphics cards are more than ample for running O, Coot, Pymol, etc. Cheers, ___________________________________________ Roger S.

Sent: Wednesday, June 20, 2007 1:24 PM To: CCP4BB@JISCMAIL.AC.UK Subject: Re: [ccp4bb] Popularity of Stereo graphics in crystallography I agree with Kevin. We have stereo on about half of our workstations, and no one has used them in about three years. We typically use "O". Also, we have three large servers which are relatively fast. So the main purpose of a workstation is building, not computing here. That way you can easily work on multiple structures on a workstation at the same time, while you're refining and building them. We have a few people that use PC's and Coot as well. Bernie On Wed, June 20, 2007 11:45 am, P Hubbard wrote: > Hi, > > Thanks for the e-mail.
