Perhaps one answer to the problem of using images might be to embed the source LaTeX (or MathML, TeX, ...) in the image so that anyone with the appropriate tool could then extract the source and edit the 'image' etc. Obviously this requires someone to provide the tools, but it coukd free us of

hi I haven't been following all the thread, so apologies if someone else has already mentioned this as a way round the original problem. having had problems with equations disappearing in a variety of WP presentation software over the years, I've taken to creating them in my program of

Hello Everybody! I was trying to make some sense from Bernhard Rupp's book page 251. I will copy the relevant part... When photons travel through a crystal, either of two things can happen: (i) nothing, which happens over 99% of the time; (ii) the electric field vector induces oscillations in

Excellent and interesting question—I’d love to hear an answer as well. Creatio ex nihilo at the synchrotron? I’d also love to hear what the evidence in the literature is for this, although I suspect much of it would be hopelessly encoded in bristling equations. (Nothing against equations, but

The answer to your questions depends on the level of understanding of quantum mechanics. I am sending info where to find the subject discussed in more details. Bernhard Rupp's book page 251 necessarily simplifies a rather complex subject of the photon's interaction with multiple particles.

Even I have the same problem my crystals get processed in to P212121 as well as P4212 and I am currently analysing the data but not able to conclude the space group. Any idea? Both structure while refining is giving around same R/Rfree. Any help will be appreciable. Dhaval Patel PhD Student,

Dear Mohamed You can get the equivalent of frame.CBF by using the duals image viewer with datablock or experiments.json and integrated.pickle. this will allow you to step through the frames looking at the actual integration boxes. Best wishes Graeme On 21 May 2015 17:02, Mohamed Noor

Dear all I can process my 3.8 A dataset in either P4 or P422 point groups. MR searches and refinement in SG P41 and P41212 results in R/Rfree of around 30/35 % with 8 and 4 NCS copies, respectively. Pointless doesn't seem to complain but Xtriage suggests 25 % twinning in the former (refinement
