How important is cutting crystals to get them entirely inside the beam? When I was at the Canadian Chemistry Crystallography Workshop when I was first learning, I seem to recall them saying that it wasn't so important these days, and that multiscan correction was good enough to handle almost anything, whereas cutting can induce errors. However, people in my lab group say that if you have the crystal larger then the beam, than the absorption correction will be wrong. I've run a few crystals rather larger then I should have, and the resulting data seems to be the same quality as similar crystals that fit entirely inside the beam, so I was wondering how important getting the entire crystal into the beam is.Second question, how likely is cutting the crystal to introduce errors?
I didn't find the right solution from the Internet.
