Hi Peter,
You can specify in DM the mean density of the protein region in the SOLC
keyword. However I am not sure this will affect the density distribution
used for histogram matching.
All the best,
Adam.
And to add another small item: the SOLOMON interface in SHARP allows
adjustment of the mean density depending on protein, DNA or RNA
content. See

Cheers

Dear Ed,
The question of dealing appropriately with density modification in the
presence of "heavy atoms" has been discussed in the paper on SHARP 2.0 (see
Acta D59, 2023-2030, published in 2003) and the solution described in that
paper has been available in all versions of SHARP/autoSHARP si

Hi Peter,
Histogram matching works well for RNA structure, but be aware that
density modification in general can be very tricky at low resolution.
If by any means you can exploit averaging, e.g. multicrystal averaging
of non-isomorphous crystals, it will probably be very helpful. It will
