Dear Paul, Thank you for your response. I wanted to compare a Coulomb potential map to an electron density map. Before aligning these maps, I need to bring them to similar parameters, which requires rescaling one map to match the other. After that, I can proceed with density subtraction.
I hope this clarifies my query. Sorry for any confusion. Thank you again.
