Dear All,
I would be thankful to you if you could suggest as how I can get the
information about absolute value of electron density in eA^-3 units.
I have a phase file containing h k l FP FOM PHI SIGFP columns produced
by SHELXE. When a simple electron density map is calculated using FFT,
I could see some map info, like sigma level (the Rms deviation from 
mean density). While one can get this information electron density
in eA^-3 from shelxpro where it reads .fcf file produced using LIST 6
command in shelxl refinement. However, I cannot use shelxpro as it can 
only read phase file containing the following columns,
h k l Fo^2 SIGFo^2 PHI (.fcf file from shelxl). So it is in this regard
I welcome any suggestions inorder to get the absolute electron density
information from the map calculated by using SHELXE phases.
thanking you in advance,
sincerely,
ram
