the crystal packings in A and B are overall similar, there
seems to be another P21 axis in crystal A, which may help to determine
the NCS parameters during phasing as there are two moleculars in the ASU.
Could anyone help to tell me how to derive the NCS parameters?

Dear All,
I got a Se-crystal diffracted to 3.3A. The protein is predicted to be a
coiled coil. After I got the heavy atom positions from a shelxd based
programs from AutoRickShaw, I run phaser and phenix.autobuild to get a
initial phase shown in the attachment. I fit a standard helix into the
Dear all,
currently, I have a data set scaled in P22121 which containing a PST of
(0.5,0.5,0.111). The structure were successfully solved by molecular
replacement. However, the R free factors remained as high as ~33% in the
refinement. I search the literature and found that it was common to
Hi,all,
I can get the R-value~resolution statistics from .lst file,but where is the
Rfree value?
Thanks in advance.
