I'd rather go for a complete low resolution dataset. Is this a native
crystal ? HA derivative ? Even with a 4Å data set you can do something
it's painful but not impossible e.g. molecular replacement if
possible. Then at least you would know your spacegroup & perhaps gain
some insights from
How about 90?
If it is ok , maybe you need more than 3 or more xtals to collect the
whole dataset and merge them together.
Otherwise your xtals should be the anisotropic .You'd better to collect
images in the better region or screen more xtals to get better ones.
Good luck!

hello everyone, I am seeking help on a crystal decay problem
I got crystals of a protein , but it decayed very fast in syncrotron beam. From
the initial index, it is P222 space group, I need about 180 images, its initial
diffraction went to about 3 A, and after 70-80 images, it droped to abo
