dino-quant
Experimental quantized DNA sketch prefilters for sequence-search pipelines.
dino-quant compresses DNA k-mer sketch vectors into small approximate codes,
uses those codes to route reads to likely reference windows, and emits candidate
ranges for downstream exact tools. It is a prefilter: exact alignment,
classification, and biological interpretation stay outside this crate.
Commands
Scope
dino-seq is the only FASTA/FASTQ input backend. Quantized candidates are a
prefilter only; exact alignment stays downstream.
emit-candidates writes target_id with each row so
emit-candidate-reference can reconstruct multi-record references even when
FASTA headers share the same first token. Minimizer reference caches are tied to
the parsed reference content and are rebuilt automatically when that content
changes.
Retrieval Modes
| Mode | Purpose |
|---|---|
scan |
Exact approximate-score scan across quantized reference windows. |
minimizer |
K-mer minimizer postings to reduce scored candidate windows. |
simhash |
SimHash bands for locality-sensitive candidate routing. |
mih |
Multi-index hashing over SimHash-style codes. |
ivf |
Coarse centroid buckets before approximate scoring. |
hnsw |
HNSW-style graph walk over retained window sketches. |
