Hi
I believe there is a bug in the Fingerprints Expander node.
Assuming Bit 1 is the first bit in the BitVector (bit 0) then the fingerprints are being reversed as they are expanded.
I don't appear to be able to access the source code in the latest SDK but from memory of an old version I believe you are parsing a BitStringrepresentation of the BitVector (which KNIME gives in a big endian way and is thus the reverse of the fingerprint in the little endian way which is output).
Found the new source: https://community.knime.org/svn/nodes4knime/trunk/org.erlwood/org.erlwood.knime.core/src/org/erlwood/knime/nodes/bitvectortobits/BitVectorToBitsNodeModel.java
Maybe I'm missing something but this looks like it is traversing in the wrong direction...?
Example:
BitString: 10000000110
Set Bits: {length=11, set bits=1, 2, 10}
Expected columns
| Bit 0 | Bit 1 | Bit 1 | Bit 3 | Bit 4 | Bit 5 | Bit 6 | Bit 7 | Bit 8 | Bit 9 | Bit 10 |
| 0 | 1 | 1 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 1 |
What I get:
| Bit 1 | Bit 2 | Bit 3 | Bit 4 | Bit 5 | Bit 6 | Bit 7 | Bit 8 | Bit 9 | Bit 10 | Bit 11 |
| 1 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 1 | 1 | 0 |
Cheers
