Hi all,
I have two datasets, both CO SAD data, one collected at CO anomalous
wavelength at synchroton and the other at home source. I wish to combine
these two data-sets and use for SAD phasing. Can anyone suggest how this
can be done?
Regards,
ARKO

Dear Arko,
could you not try MAD with the two different data sets?
Otherwise you can check the strength of the anomalous signal for both
sets separately (I am sure pointless prints the anomalous CC over
resolution shell) and after merging them.
If
How to merge two or more runs depends on the software you used to
process the images. If you used MOSFLM/CCP4, then you would use the
programs REBATCH (perhaps REINDEX) and SORTMTZ to combine the unmerged
mtz files (the ones that come out of MOSFLM) before feeding them to
SCALA. My program

By the way, I wouldn't use MAD to describe the mergeing of non-isomorphous
datasets. Strictly speaking, MAD is at least an attempt to measure both
anomalous (f) and dispersive (f') differences, and I don't think it is
appropriate to use the term MAD when you know the dispersive signal is
Isn't it true that we cannot even agree on what MAD stands for?

That is excellent! You refer obviously to the multiple anomalous

Hi,
Regardless of what the consensus on naming for the technique, I'd
suggest you combine these datasets during phasing (I'm aware of MLPHARE,
SHARP, PHASIT supporting multiple anomalous datasets during phasing;
others probably do as well). Combining at the merging step

I wish you could, but I don't think so, because even though those
