From your picture it looks like you have both these needle clusters and single
needle/rod-lke crystals. The diffraction pattern you show is what you expect
from a needle cluster (with the ring-like patterns at low resolution), a single
needle or a larger optimized single crystal should give you
Dear Yujie,
At first I thought this looked just like diffraction of multiple salt crystals,
but there are perhaps a couple of rows of regularly spaced spots from a protein
crystals. However, I think any program will struggle to get anything useful
from this.
Perhaps focussing a small beam
Yujie,
I would try using another processing program if you have it available, say
Mosflm. I look at similar looking diffraction data recently, though without
the salt crystals mixed in as Herman observed which you also need to take care
of in the future, and HKL did not handle if very well,
