ACO

ACO compresses quality scores from high-throughput sequencing losslessly to reduce storage and preserve fidelity for downstream genomic analyses.

Key Features:

• Lossless Compression: Ensures no information is lost during compression, preserving the integrity of sequencing quality scores.
• Adaptive Coding Order: Traverses quality scores along trajectories that reflect their correlations with the sequencing process to optimize compression pathways.
• Arithmetic Coding and Context Modeling: Integrates adaptive arithmetic coding with context modeling to enhance compression effectiveness while maintaining moderate computational complexity.

Scientific Applications:

• Genomic data preservation: Maintains fidelity of quality scores from high-throughput sequencing for accurate interpretation of sequencing results.
• Downstream analyses support: Preserved quality-score information supports downstream genomic analyses that depend on score accuracy.

Methodology:

Reinvestigation of correlations between quality scores and the sequencing process informs an adaptive coding order that navigates quality-score trajectories; the approach combines adaptive arithmetic coding with context modeling to maximize compression efficiency without compromising data integrity.
