[Rdkit-discuss] RDKit fingerprints in Knime - operations on DenseBitVectorCell

2014-02-28 Thread Michal Krompiec
Hello,
I am trying to implement substructure searching with fingerprint-based
screening in Knime, using RDKit fingerprints (I know that a database
would be the preferred solution, but for some reasons I'd rather use
Knime).
In order to do this, I need an equivalent of
DataStructs.AllProbeBitsMatch() function (or at just logical operators
on DenseBitVectorCell) - is it possible in Knime? Or otherwise, is it
possible to convert a DenseBitVectorCell column to something else?
Best wishes,
Michal

I'm afraid that I don't know how to do this from within any of the knime
nodes.
We currently have an item on the ToDo list for the RDKit nodes to allow
using fingerprint-based screening to make substructure searching faster.
The bit operations are clearly usable at the java level. I'm not 100% sure
what the timeline is for completing that work (I need to check with
Manuel), but it shouldn't be too long.
