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
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
- Type: Data Input table containing two fingerprint columns of the same type. Acceptable fingerprint formats are SparseBitVector, DenseBitVector, SparseByteVector, DenseByteVector.
- Type: Data Output table with subset fingerprints
