Subject: How to subtract one electron density map from another From: Qing Xie qingxie {- at -} MAILER {- dot -} SB {- dot -} FSU {- dot -} EDU Date: 2007-03-22
Hi, I'm trying to get the difference map by subtracting the native electron density map from the complex electron density map. MAPMASK has a function of ADD/MULT, but I don't know how to use it? Any other ways to attack this problem in real space?
Thanks in advance,
Qing
