Nakane-san, There is also CrysAlisPro, which can handle multiple crystals and may already support your detector. If you send me the data, offline, I would be happy to pass it onto the CrysAlisPro development team for testing.

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.

For quasicrystal and modulated crystals, "dials.rs_mapper" is also very useful. Best regards, Takanori Nakane > Have you tried microseeding of these sphere crystals?
