Fingerprint SUBSET

StreamableVernalis Fingerprints extension for KNIME Workbench version 1.30.2.v202106181332 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

Options

Select the fingerprint column: Select the incoming fingerprint column
Keep input columns: Keep the input fingerprint column in the output table?
Start: The first index to be kept (0-indexed)
End: The first index to be lost, or -1 to run to the end of the fingerprint

Input Ports

: Input table containing two fingerprint columns of the same type. Acceptable fingerprint formats are SparseBitVector, DenseBitVector, SparseByteVector, DenseByteVector.

Output Ports

: Output table with subset fingerprints
