Thanks for the quick response. I just listed out

Dear Lijun Liu,
You can use the CCP4 prog sftools to determine if there are
just a few strong reflections.

Hi all,
I solved a structure and the refinement is close to complete.
However, some residual density puzzles me.
The SG is P212121,
Could any of those strong spots at 2.1 be ice?

Hi,
It looks like the data is highly anisotropic - I've seen it many times.
You can either apply anisotropy correction
(http://www.doe-mbi.ucla.edu/~sawaya/anisoscale/) or use PHENIX tools to
compute the maps - anyone of both should help. The major difference
between the two is that PHENIX
