Joe,

UCSF Chimera will allow you to do this if you open your pdb file then open your ccp4 map and select one of the monomers. This allows you to display the map only on the selected zone. Next, you just have to open the map again, which allows you to display the map for the other monomer and color it differently. The UCSF Chimera program website is below. If you need any more help don't hesitate to email me.

Thanks a lot for the replies I have received so far!

I have one homodimer in each ASU. What I intended to do is to show the electron density for each monomer in different colors (only for presentation purpose). I guess the only way to achieve this is to individually create (not sure it is a right word) the map for each monomer and then display them in pymol or coot. Any better solutions?

Thanks,

Joe

Hi,

I want to generate maps only covering atoms in the pdb file. I tried fft-creat map in ccp4i (output map to cover all atoms in pdb), but it actually also generated map in places other than pdb atoms. Are there any other ways to do this? Thank you.
