Abstract excerpt
Somatic variant discovery in tumors is crucial for clinical analysis, yet most existing methods are designed for short-read sequencing, with few developed specifically for long reads. Here we present Clair-Somatic (ClairS), a deep-learning-based somatic small-variant caller designed for long-read tumor-normal pairs. Trained on synthetic somatic variants with diverse coverages and variant allele fractions, ClairS...
