Hi Dorothee and Billy,
Thank you for your information! I have both I, SIGI and IPR, SIGIPR labels
in my unmerged MTZ (I checked this with ViewHKL). But it seems the Xtriage
only offers choices to merged mtz. I tried to choose I,SIGI, Merged option
(even though my mtz is unmerged), the Xtriage output shows "anomalous flag
false" and I did not get any additional anomalous information from the

>> Dear Phenixbb members,

>> ctruncate_xxx-unique.mtz. After I check with viewHKL, I found the only
