[ccp4bb] fix or scale bfactors during processing?

[Francis E Reyes]

Hi all

I have pretty low res data (4-4.5A) and was wondering what's the  
suggestion for allowing the bfactors to vary or keep them fixed during  
scaling. If I fix them, xtriage reports wonderful anomalous signal  
whereas if they are varied, the anomalous signal is gone. I have  
natives and suspected derivatives so MIR is possible. Rmeas's are  
pretty similar independent of whether I keep them fixed or allow them  
to vary. Is there a more sensitive statistic (to whether or not to  
scale or vary bfactors) that I'm missing?

Thanks
FR
