 Hi,
 I converted my check point file to .fchk and then to .cube.
 Then I tried opening it in chemcraft. When I opened it to view the electron
 density, I see only atoms with positive density. How do I get it to show me both
 positive and negative regions? I am very new to this and would appreciate any
 help.
 Thank you
 Madi
