Hi:
I have two set of data from the same crystal with the names 1.sca and 2.sca,
they have different Intensity values due to different scale factors.
Now I use Scalepack2mtz
convert them to 1.mtz and 2.mtz, then use cad to merge to a cad.mtz, then
convert it to cad.sca file, I find that the Intensity values in this
cad.sca arediffrent from
1.sca and 2.sca, I wonder if the program has scaled the values itself?
If that is true,
which program did this, Scalepack2mtz or cad?
Thanks!

Li Yang
