Dear Prof. Dodson:
Thank you for your kindly suggestions.
Actually, the sg we predicted was P4222. However, the systematic absence was
showed alone 00l in the log file(In below).
Is ant conflict on that?
Thanks again I appreciated.
Sincerely,
jaishin

Dear All:
We have a crystl with P4222 sg.
All statistics look fine.
However, there is a system absense in l axis.
Any body have experiences on that?
Any suggestions would be high appreciated.
jaishin
can you give more details, eg all reflections along the particular axis..
Things like ice rings or overlapping intensity from a next neighbour
getting integrated inapropriately can cause anomalies..
