Dear all,
one of my colleagues has probably a twin and he can't find the good
solution or the twin law.
Using XDS he has obtained the space group P212121 and a unit cell of a=
55.54 b= 60.72 c= 121.4 and all angles are 90°.
In this unit cell b is approximately equal to 1/2 c.
Datas are good for 1.9A resolution and a solution can be found by
molecular replacement.
Peaks of Rotation Function (Rf/sig)
1- 11.48
2- 6.80
3- 4.25
...
Translation function (Tf/sig)
1- 8.13
2- 5.21
3- 2.70
...
It is possible to make refinement but the electron density is not good
and it is not possible to decrease the Rfree under 33.00%.
If somebody can help me ...
Regards
