Hello, I have run into a very odd situation. Upon collection and data processing on a crystal on my home source all pointers seemed to show twinning. Was not surprised since previous crystals under different but related conditions have showed significant twinning though the cell dimensions were different but not the resulting apparent space group.
Now the odd thing, I sent the crystal to the synchrotron figuring I might be able to get some data that might help figure out what is going on. Upon processing of the synchrotron data, SSRL 9-2, magically no twining was detected. A couple of other crystals of the same compound though not from the same exact condition showed the twinning. I processed the data using HKL, which I primarily on my home source data and XDS with similar results. In summary, the exact same crystal shows twinning on Cu home source and no twinning at all at the synchrotron. Any ideas would be welcomed.
