Looking at the P422 data, it look like you have pseudo translational symmetry. Did you try processing this data as I422?
From the P422_xtriage.log:
The full list of Patterson peaks is:
x y z height p-value(height) ( 0.500, 0.500, 0.165 ) : 78.635 (6.634e-07) ( 0.000, 0.000, 0.330 ) : 56.292 (2.795e-05) ( 0.500, 0.500, 0.497 ) : 30.920 (1.207e-03)
One word of caution: an exceptionally high off-origin peak can mean that the unit cell was measured too large, and you've integrated extra reflections that are really non-existent. (I'm not sure what the threshold for this is, but 80% seems pretty large.) Splitting and various indexing artifacts can sometimes lead to this. I'd recommend running labelit.index on the images and seeing what it thinks the lattice should be. -Nat
