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
Hemisphere).

I have learned to refrain from catapulting my crystals.
Happy holidays, God bless us ... everyone (with diffracting crystals)

Sadly, I have seen numerous examples of reasonably-sized crystals that give no
observable ordered diffraction (I shot a few this weekend, in fact). I can’t
give you evidence for what is happening, but I guess that you can build a
macroscopic ass

Dear ccp4b collective mind and experience,
Greetings from San Diego.
I have done my fair share of synchrotron data collection on many diverse
macromolecular crystal systems. But this weekend was the first time that I
ever shot crystals that failed to diffract entirely.
