type="cite">Dear James,
your challenge in its current form ignores an important
source
of information for model building that is available for your
simulated data - namely, it does not allow to use anomalous
phase information in the model building. In difficult cases
on
the edge of success such as this one, this typically makes
the difference between building and not building.
If you can make the F+/F- and Se substructure available, we
can test whether this is the case indeed. However, while I
expect this would push the challenge further significantly,
most likely you would be able to decrease the Se
incorporation
of your simulated data further to such levels that the
anomalous
signal is again no longer sufficient to build the structure.
And
most likely, there would again exist an edge where a small
decrease in the Se incorporation would lead from a model
built
to no model built.
Best regards,
