I understand you want to use in situ diffraction for assigning scores,
but I guess it is still useful to visually inspect drop images before
you decide to go to a synchrotron, no?
So let me rephrase the question and ask whether users see any added
benefit of using an iPad for decision making on 'going to a
synchrotron/buying Marcus's PX scanner' or not.
Thank you for the private posts indicating we now have a good excuse
to buy iPads from research grants. Unfortunately for the PI's, we may
have to buy them for all lab members now.
Would also be interested to find out if there are any members of the
crystallography community that have experience in writing iPad apps.
Cheers.

I agree with Marcus that the most relevant scoring is the X-ray
analysis, that can now be done in situ.
Just I would like to mention the G-Rob system we developed for that on
BM30A at ESRF, now commercialized by NatX-ray (www.natx-ray.com).
With G-Rob, you can not only screen in situ, but also collect complete
dataset "in plate" (and also on frozen samples, capillaries, ...)!
See http://www.natx-ray.com/products/clip_IE_March2010.html

PS: G-Rob is available on beamline BM30A at ESRF. Don't hesitate to
ask for beamtime.

Dear Chris,
I’m prompted by your posting just to mention the Agilent Technologies
PX Scanner ‘Crystal Challenge’ at:
www.agilent.com/chem/crystalchallenge
Thus, the only really useful assessment, or ‘score’, of objects
(putative
crystals) – or crystallisation conditions, is by the actual observed
diffraction
characteristics... and these preferably directly in situ, in the
horizontal
crystallisation plate, as achieved in the PX Scanner.
Many Thanks and Best Regards,
Marcus Winter (Agilent Technologies)

Subject: [ccp4bb] viewing and scoring crystallization drops on the
iPad
Our laboratory has been developing an application to view and score
crystallization drops on the iPad. We would like to know if
crystallographers see potential benefits from the functionality of
the iPad to swipe and pinch through drops. We are looking for
specific comments from Formulatrix users, but other users are also
welcome to comment.

Specific ideas for future development are:
- composition of crystallization buffers on a back-flip of the image
drop
- back-sync of crystallization scores on the iPad with the image
database
- emailing a drop image to colleague
Thanks.
-Chris
