Dear Pavel,
I had a try today for feature enhaced maps on 3.7 and4 A resolution datasets.
The maps look great and I feel especially at low resolution this new tool  helps a lot to interpret the maps.
I would be very much interested to test the fem for e-densities calculated from experimental phases. Is it possible in the future to use heavy atom derived phase information instead of a model to calculate FEMs?
Best wishes,
Guenter

Hi Joseph,

Thanks Nat! I am trying out the new "Featured Enhanced Map" option.
Preliminary analysis says it really helps!

Okay, that definitely isn't included in the GUI yet - I was waiting to
hear from Pavel before I added it.

I am sure Pavel would be interested in seeing any cases where this
helps.  In general, although we obviously test new methods against
existing datasets, it is always more impressive to demonstrate that
they help solve new problems.

I'm glad it worked for you, and I'm very interested to hear any feedback or answer questions. This is still considered under development, though current implementation is stable and ready to use. There might be some changes to the algorithm in future (mostly to make it faster, so it can be routinely run after refinement, for example), but I don't think these changes will be major.

The only documentation at present is this set of slides:
http://www.phenix-online.org/presentations/fem.pdf
which also provides usage instructions (using command line).

Nat: yes, it would great to have GUI for this! Thanks!

Pavel
