Fingerprint SUBSET
StreamableVernalis Fingerprints extension for KNIME Workbench version 1.20.5.v201908130849 by Vernalis (R&D), UK
This node performs a logic SUBSET operation on a selected binary (bitvector) or count (bytevector) fingerprint column.
The start value is inclusive, i.e. the value is the first bit or byte included in the subset (0-indexed). The end value is the first bit or byte to be excluded. Use '-1' to retrieve to the end of the fingerprint.
If the start index is beyond the end of the fingerprint, a zero-length fingerprint is returned
Examples
Fingerprint '01100110'
Start = 3, End = -1 returns '00110'
Start = 0, End = 3 returns '011'
NB Binary fingerprints are rendered in bigendian format, and so index 0 is the right-most displayed bit, whilst for count fingerprints the counts are in increasing order of index
This node was developed by Vernalis Research. For feedback and more information, please contact knime@vernalis.com
