[Chimera-users] visualizing density map

[Walter R.P. Novak]

Hi Francesco,

I am not sure if this is also an issue in how the map was generated.  
Using FFT in the CCP4 suite, you should generate the 2Fo-Fc map in  
CCP4 format and format the map to cover "all atoms in PDB file." If  
your PDB file contains the region you want to view, you should be all  
set. You can also extend the map a certain number of Angstroms in  
FFT, the default is a 5 A border.

Best,
Wally
