Hi,
In crystallography one of the features of a good map is that the histogram of
map values has skewness. Does this also apply to EM maps? Whereas X-ray maps
depicts the electron density EM maps depicts the electrostatic potential as I
understand it. Any pointers about skewness or not in EM ma
Hello,
This was discussed on the CCPEM list recently, see this discussion:
https://www.jiscmail.ac.uk/cgi-bin/wa-jisc.exe?A2=CCPEM;dda7f5e8.2310 (you can
navigate to the answers with the "By topic: Next" link at the top).
I hope this helps,

Hi Rob,
the fundamental property of crystallographic or cryo-em maps -- the
presence of high density points -- is what skewness depicts. So I can't see
why the idea of using skewness to quantify maps would be any different for
x-ray vs cryo-em. I've just downloaded a cryo-EM map for this (PDB: 8d3y
Thanks for the replies and the links with more information.
