[OpenBabel-scripting] SMARTS excluding

[Jurgens de B. <deb...@gm...>]

Hi,

I am searching for a number of active groups in molecules using smarts and
it so happens that some of the groups overlap. Thus would it be possible to
write a smart stating to find a group but it should not be part of another
group.

smartA = "Some Smart"
SmartB ='SecondSmart not part of SmartA'

Thanks
