Hi Eleanor, what you say is of course true, particularly in the case of the 1st dataset where probably the indices go down to 52 Ang. but the measurements only start at 36 Ang.  But still it's hard to see how for the 2nd dataset, if the low res cut-off of the indices and/or measurements is 57 Ang., it manages to 'use' a reflection at 104 Ang.  All depends what you mean by 'use' of course!

Cheers

The resolution limits of the measured data are not changed but your output file must contain all possible h k l even if there is no observations for the lowest resolution ones..

dont worry about it!

Dear crystallographers,

I have two datasets that were merged/scaled using ccp4's aimless, with resolution ranges of 52-1.7 and 57-1.9. However, upon refinement, the resolution range used by phenix.refine is 36-1.7 for one and 104-1.9 for the other. 1) Why does phenix.refine change the low resolution limits of my processed data? 2) How can I prevent this?

Thanks,

Andrew
