If that solution applies to the original model you used (and not to re-solving
the structure with the molecular replacement solution before or after
refinement), then your tetramer model is just being rotated by 90 degrees
around the 4-fold and placed on a different origin, i.e. the solution is
Hello,
What about the enantiomorphic space groups (the 4(3) screw axes instead
of the 4(1) screw axes) ? These cannot be distinguised on the basis of
structure factor amplitudes (unless you have an anomalous scatterer) nor
on the basis of the specific extinctions (both screw axes extinguish th
Hi, Dear CCP4 group,
I recently collect one dataset and indexed as P4 space group. When I try to do
MR with a tetramer as input, I found the solution file suggested P41.
