Dear Bernhard
I am wondering where I should cut my data off. Here is the statistics
from XDS processing.

Dear all,
I got a reviewer comment that indicate the "need to refine the
structures
at an appropriate resolution (I/sigmaI of>3.0), and re-submit the
revised
coordinate files to the PDB for validation.". In the manuscript I
present
some crystal structures determined by molecular replacement using the
same
protein in a different space group as search model. Does anyone know the
origin or the theoretical basis of this "I/sigmaI>3.0" rule for an
appropriate resolution?
Thanks,
Bye,
Roberto.
