Hi Daniele,
we had a possibly similar case and in collaboration with Andrey Lebedev
we demodulated the data using different methods including a novel
method, DIGS, (see Acta Cryst. (2014). D70, 1680–1694). We have a few
scripts to analyse the data and to use the described methods. Sadly we
never got around to make this more user-friendly and/or put into a
server (probably not even such a high demand?!). Anyway, if you wish we
can dig out the scripts and try to get the scripts working on your data
(depending on the disorder).
Would be good to figure out the SG etc before though... Note: pseudo
precession diffraction pattern (e.g. from labelit) can help in analysis
of the data.
Cheers,
B

Hi all,
I'm currently dealing with what I think it is a case of LTD (off-origin
Patterson peak, with vector along w of ~ 7A and electron density map
showing a "ghost" map shifted by 7 A). I saw there are quite a few cases
reported in literature (for example Hare et al, 2006), but what I could
not find is how I can demodulate the data. Is there any software that
can be used for this?
Thank you
Daniele
