pre-filter for querying very large collections of nucleotide sequences


Raptor is a system for approximately searching many queries such as next-generation sequencing reads or transcripts in large collections of nucleotide sequences. Raptor uses winnowing minimizers to define a set of representative k-mers, an extension of the interleaved Bloom filters (IBFs) as a set membership data structure and probabilistic thresholding for minimizers. This approach allows compression and partitioning of the IBF to enable the effective use of secondary memory.
