Dear all,
I have an orthorhombic crystal (pointless suggests most likely space groups P 2 21 21 or P 2 21 2)
with two molecules expected in the asymmetric unit. Analyzing the native Patterson map I found the
following peaks (in fractional coordinates):
CELL 63.0400 117.2500 133.6500 90.0000 90.0000 90.0000
ATOM1 Ano 0.0000 0.0000 0.0000 111.03 0.0 BFAC 20.0
ATOM2 Ano 0.0102 0.0416 0.0000 15.98 0.0 BFAC 20.0
ATOM3 Ano 0.0000 0.5000 0.0037 6.21 0.0 BFAC 20.0
ATOM4 Ano 0.0669 0.0850 0.0000 5.86 0.0 BFAC 20.0
ATOM5 Ano 0.0772 0.4168 0.0000 5.78 0.0 BFAC 20.0
ATOM6 Ano 0.1139 0.1196 0.0049 5.10 0.0 BFAC 20.0
The third and fifth are far enough from the origin to represent tranlations. Is the third due to an
alternative origin? Could the fifth represent a pseudo-translation?
Thanks,
Michele
