Dear Edward: I generated two maps in the same way, load them in MAPMAN, then normalize them and PE VA them. I think after normalization, the out put electron density value at each atom should be equal to the sigma.
Now the problem is, the output denisty values seems "squeezed" in the pdb file format, so some lengthy values were not printed correctly. Do you think there is a way we could avoid it? By the way, can MAPMAN automatically read all the paramters at the same time so that I can run them at background? Or I have to enter MAPMAN interface and type each comman one by one? Thanks a lot!
