[Pw_forum] Displaying charge density difference

[Ozan Dernek]

Hi, 
I want to display the difference of charge densities of a bimetallic structure by using VMD.
But the .cube file has only the charge density information. Is it possible to obtain charge density difference by using weight flag or should I do separate calculations ? (For both cases an explanation about how to do them will be much appreciated.)

Cheers, 
Ozan
