[ccp4bb] PISA standalone
Hello CCP4 people! I was wondering about the status of the PISA standalone version. The powerpoint slides of the CCP4 meeting in march 2007 ( http://www.ccp4.ac.uk/dev/CCP4_meeting_270307/session_8/3_pisa.ppt ) say that the standalone version by Eugene Krissinel is finished and includes screenshots too. However i cannot find the program in the CCP4 6.0.2 package nor can i find any further information about it on the ccp4 website or this mailing list. Am i missing something, or is it not included? Is there any way to obtain it? Regards, Patrick Hollerein
Re: [ccp4bb] PISA standalone
It is scheduled for 6.1 It works for me, but you need to sort out things like having the latest SSM and MMDB libraries and a few environment variables to set. Email me if you want to beta test it for us ;-) Martyn On Tue, 2007-11-27 at 11:19 +0100, Patrick Hollerein wrote: Hello CCP4 people! I was wondering about the status of the PISA standalone version.

[ccp4bb] ccp4i integration task
Hi folks Can you reply directly to me rather than ccp4bb? I was wondering how many people out there actually use the integration task in ccp4i? We're trying to work out how much support it needs, and how it needs to be developed, so comments on usage, problems, etc. would all be gratefully received!

Oops, sorry. The x axis of the previous plot is actually not resolution, but Q. My bad.

I don't recall if the plot is corrected for CCD pedestal values, so the difference is not quite as dramatic as x49, still very nice clean background if you are looking for a faint signal. The CCD images below are equal exposures shown with equal contrast settings: HeN2.tiff HeN2imgs.tiff
Re: [ccp4bb] To bathe or not to bathe.
Richard I think the sharp spot is just small angle scattering (e.g. from domain boundaries) resulting from the beam hitting one of the defining apertures in your collimation system. If you ray trace the beam from the last defining aperture, through the guard aperture then to the detector you should get an area of high background where the guard aperture does not cut this off and it is not covered by the beamstop. It then drops off as the beamstop comes in to play appearing to give a sharp spike. In fact, it is quite well set up with the beamstop not overly large. The appearance of a very diffuse ring for the scatter from nitrogen is due to the fact that the beamstop cuts off the air scatter, for the parts of the beam nearer the beamstop.
