BitVector NOT operation

Hi,

Is there a way to do a logical NOT operation on one BitVector column compared to another? The column aggregator node doesn’t seem to offer that operator, although it does allow AND, OR and XOR. The Vernalis Fingerprint NOT node simply does a NOT on a single BitVector i.e. the complement.

I need to be able to do the following:
........FP1 0001111111
........FP2 1111110000
FP1 NOT FP2 0000001111
…where FP1 and FP2 are in separate columns and FP1 NOT FP2 needs to be a new column.

Any ideas?

(FP1 XOR FP2) AND FP1?

(I.e an XOR node followed by an AND)

Ah, thanks Steve.
I thought there was probably a way to do it with the other operators, but couldn’t see the solution.

Cheers,

Richard
