[ccp4bb] space group problem

[Junyu Xiao]

Hi all,

We run into an interesting space group problem. The same diffraction  
image can be either indexed into space group C2, with a=145, b=44,  
c=67, and beta=110.5; or space group P2 (should be P21 after  
scaling), with a=67, b=44, c=136, and beta=96.8. Both are refined ok  
during index. These two must somehow be related. Can anyone give some  
comments on that?

Thanks a lot,
Junyu
