Yep. Or at list run some "crystall recognition software" to extract coordinates of interesting stuffs in the drop... 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. G-Rob systems are not only available on synchrotron, but also as complete in-house systems for labs (with source and detector, etc.) 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. as for rewriting some automated scoring programs already available on some other systems.

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, ...)!

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. http://www.youtube.com/watch?v=LezurNhm0pA   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   --------------------------------------------------- Chris Ulens, Ph.D. Lab of Structural Neurobiology Department of Molecular Cell Biology Campus Gasthuisberg, ON1 Herestraat 49, PB 601 B-3000 Leuven Belgium http://www.xtal.be   -- Jean-Luc Ferrer |-------------------------------------------------------| |Institut de Biologie Structurale J.P.
