SKSV

SKSV detects structural variations from circular consensus sequencing (CCS) reads using a skeleton-based approach to enable fast and accurate SV discovery.

Key Features:

• CCS read support: Operates on circular consensus sequencing (CCS) reads for structural variation detection.
• Skeleton-based methodology: Implements a skeleton-based approach that focuses on essential alignment information rather than generating exhaustive read alignments.
• Reduced computational overhead: Reduces the computational demands typical of alignment-based SV detection workflows.
• Processing speed: Achieves an order of magnitude faster processing speeds compared with state-of-the-art SV calling approaches.
• Accuracy: Delivers higher accuracy with improved F1 scores across multiple types of structural variations.
• Benchmarking: Validated on both real and simulated datasets to assess speed and accuracy trade-offs.

Scientific Applications:

• Rapid SV discovery: Enables rapid identification of structural variants in CCS sequencing experiments.
• Large-scale genomic analyses: Facilitates large-scale SV cataloging by lowering computational cost for population-level studies.
• Complex genetic architecture: Supports exploration and characterization of complex structural variants relevant to genetic architecture and disease studies.
• Method benchmarking: Serves as a reference for benchmarking and comparative evaluation using simulated and real datasets.

Methodology:

Uses a skeleton-based computational approach that extracts essential alignment information instead of producing full read alignments and was benchmarked on real and simulated datasets.
