Hello forum,
I am not sure if I should post this in the bug reports or just in the functionality subforum but I have the following problem.
I have a database of around 1800 molceules and I try to specificall look for amines while filtering out alpha and beta aminoacids. In the structure filter search I tried exluding -R(N,O,S) and =O as this would indicate a carboxylgroup or carboxyl derivatives.
The problem is that it still shows aminoacids after i used the filter with the exclude groups. I suspect it has to do with trying to use two exclude groups as there is no problem if I want to exclude a single group.
