There are programs which are good at indexing patterns from multiply
twinned crystals. Bruker AXS has one, to my knowledge. There may be other
sources. I suggest you try that first before you invoke a quasicrystal
explanation.

X-ray spectroscopy. If you took the data at a sync. source there is
possibly equipment for it built into the beam line.

I agree with Roger Rowlett, try a room temp capillary mount. Also ,what is
the magnification of the microscope/TV system you are using to center these
tiny crystals? Centering the loop is not enough.

Realistically, if you live in the US and 5 SCOTUS judges agree you can
patent anything.

I am not happy with an Rmerge of 20%. Also what is the Rmerge and
redundancy in the highest shell, i.e. do you really have the resolution of
2.9?
How did you collect this data? SR or lab.

I call these crystals as examples of Space Groups 231 where all reflections
are systematically absent.
Happy Solstice to everyone. The will be more daylight tomorrow (Northern

What is wrong with using Rfree until the very late stages of refinement,
then alternating refinements with all reflections and Rfree reflections
while not introducing more refinement parameters.
This way you would get a structure and e-map based on all the data while
ensuring that the data has not
many of us are one co-author away from each other?

We will shortly be installing a new HP computer for protein crystallography
calculations and e-map fitting.
The operating system is OS X10.5.
Has anyone advice on installing programs O, COOT, CCP4 etc on this system?

and a good check of the Space Group and a check on
radiation damage/ crystal slippage and cell parameter changes during data
collection.
I suggest this compromise between no or all images as good for the review
process without the need to have everything online.
