FinaleToolkit

FinaleToolkit accelerates the extraction of cell-free DNA fragmentation features from whole-genome sequencing data, enabling genome-wide analysis of fragmentation patterns for cancer early detection and other liquid biopsy applications.

Key Features:

• Fragmentation Feature Generation: Generates comprehensive fragmentation features including end motif and window protection score (WPS) from large cfDNA genomic sequencing datasets.
• High-Speed Processing: Processes genome-wide WPS features from a ~100x cfDNA whole-genome sequencing dataset with over 1 billion fragments in 0.7 hours.
• Memory Efficiency: Achieves up to ~50-fold increase in processing speed compared to original implementations while maintaining low memory usage.
• Arbitrary Genomic Interval Analysis: Enables genome-wide analysis of fragmentation patterns over user-specified genomic intervals.

Scientific Applications:

• Cancer Early Detection: Supports genome-wide fragmentation pattern analysis to boost performance in non-invasive cancer screening and detection.
• Liquid Biopsy Biomarker Discovery: Facilitates extraction of cfDNA fragmentation features as non-invasive biomarkers for disease diagnosis and prognosis.
• cfDNA Fragmentation Research: Enables characterization of end motif and WPS features in cfDNA genomic sequencing studies.

Methodology:

FinaleToolkit implements optimized computational algorithms for extracting fragmentation features from cfDNA whole-genome sequencing data, with benchmarking against original approaches or implementations to confirm efficacy.
