Re: [ccp4bb] double cell dimensions between P2 and C2

I agree with Phil. A P2 crystal with nearly perfect noncrystallographic translational symmetry (~1/2,~1/2,0) will look like a C2 cell with twice the length along a and b and weak spots between the indexed spots. Look for those spots on your "C2" images. Dale Tronrud On 11/9/2017 3:06 AM,

Re: [ccp4bb] double cell dimensions between P2 and C2

Dear Markus, I have seen something similar before, I think it was only one cell dimension that was changing (and not the lattice type), but it could double or triple the cell edge, crystals grown in very similar conditions, impossible to tell from morphology what the cell

Re: [ccp4bb] double cell dimensions between P2 and C2

You should look critically at the indexing of the images for both cases. Does the lattice interpret all spots, or are half of them missing > On 9 Nov 2017, at 10:02, Markus Heckmann wrote: > > Dear all, >> From a small protein, gives crystals P2 with cell > Cell
