deBGA: read alignment with de Bruijn graph-based seed and extension
Bibliographic record
Abstract
MOTIVATION: As high-throughput sequencing (HTS) technology becomes ubiquitous and the volume of data continues to rise, HTS read alignment is becoming increasingly rate-limiting, which keeps pressing the development of novel read alignment approaches. Moreover, promising novel applications of HTS technology require aligning reads to multiple genomes instead of a single reference; however, it is still not viable for the state-of-the-art aligners to align large numbers of reads to multiple genomes. RESULTS: We propose de Bruijn Graph-based Aligner (deBGA), an innovative graph-based seed-and-extension algorithm to align HTS reads to a reference genome that is organized and indexed using a de Bruijn graph. With its well-handling of repeats, deBGA is substantially faster than state-of-the-art approaches while maintaining similar or higher sensitivity and accuracy. This makes it particularly well-suited to handle the rapidly growing volumes of sequencing data. Furthermore, it provides a promising solution for aligning reads to multiple genomes and graph-based references in HTS applications. AVAILABILITY AND IMPLEMENTATION: deBGA is available at: https://github.com/hitbc/deBGA CONTACT: ydwang@hit.edu.cnSupplementary information: Supplementary data are available at Bioinformatics online.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
