Hi all,
I was wondering if someone would mind explaining how I generate an
anomolous difference map in CCP4 starting from an MTZ file...

I know that the F+ and F- are preserved in the MTZ (from d*trek) but their
precise relation to the DANO labels eludes me...
Trying to use FFT and supplying the MTZ just gives me a big volume of
0's...
 
I did generate the map with CNS, and I know the signal is there (iodine
peaks from iodobenzene), but I would like to be consistent in my analysis
sticking with CCP4.
 
Many Thanks,
Maneesh Yadav
