Error of Fingerprints Expander Node


I wanted to used the 'Fingerprints Expander' Node to process my BitVector data since KNIME Java can only recognize BitVector as String variable. I can execute the node if I use BitVector size of  8192 (power of 13) or below.

However, if I want to execute BitVector size of 16,384 (power of 14) I get the error saying: Execute failed: For input string: "."

What does it mean by that error? For your information I use RDKit Fingerprint to generate the fingerprints.

Thank you.



Can't really answer your question but I'd recommend using the expand bit vector node from the core KNIME release.
