Re: [ccp4bb] strange X-ray diffraction diagram――RNA Or Complex？

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

Re: [ccp4bb] strange X-ray diffraction diagram――RNA Or Complex？

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 (ide
