Dear Qixu Cai,

MAD phasing is based on the comparison of Bijvoet-pairs, i.e. I(hkl)
with I(-h-k-l), both within one data set and between data sets.
Therefore you might get better results if your integration program does
not assume Friedel-pairs to have identical intensities, even though
the difference is probably only marginal (integration programs do not
merge data).
So it is safest click on 'anomalous' for all data sets involved .
