The 2nd peak is a shoulder of the origin peak at 1.0 0 0 so should be
ignored..
The 3rd peak is 16% of the origin - rather marginal I would say. So I
dont think there is clear evidence of translational NCS

Morning all
Apologies for the simple question. I have a structure I would like to
solve using molecular replacement. I am a bit confused by the patterson
peaks. There appears to be a large non-origin peak (although it is
apparently symmetry-related to the origin?). Does this mean that there
is some translation occurring in the asymmetric unit? Or is there
non-crystallographic symmetry? Does anyone know what I should do to
address this? I have continued with the molecular replacement as normal
and did not get a solution with Phaser. Molrep gives a solution that
appears correct based on the maps and refines reasonably well.
