Hi Satya Dev,
You can feed the mtz output of SCALA to Phenix Xtriage and then see the
presence of t-NCS and/or any other crystal pathologies. Another thing you
can do is to merge and scale the data in P222 and then let the Phaser
decide the best space group. Again, I am curious, when you ran point
I think CCP4MG does this very selectively?

You dont say whether there is Non cryst translation - that will be reported
at various stages - the pointless/aimless/ctruncate task gives it.
But if it exists and the translation ihas a component of .5 along any axis,
that makes the SG estimate a bit uncertain - the absences could be due to
the N
Hi,
I have seen cases where in a correct space group
'R-work and R-free values 0.25 and 0.32 respectively'
at 2 A resolution sound like not too bad values.
In some of such cases when data from a different crystal
in the same space group was available R-factors were much lower
when the structure w
Hi,
I was just going to make the same point! The only thing to add is that, if
there really is translational NCS (which is certainly possible with 4 copies in
the a.u.), then it’s essential both to account for it (which current versions
of Phaser should do automatically, if you search for all
