SPAligner

SPAligner aligns long diverged molecular sequences to assembly graphs to enable accurate mapping of third-generation sequencing reads and detection of genes and haplotypes in genomic and metagenomic datasets.

Key Features:

• Graph-Based Alignment: Utilizes assembly graphs representing sequences as nodes and edges to accommodate complex genomic structures during alignment.
• Handling Long Diverged Sequences: Aligns sequences with substantial divergence to support evolutionary and comparative analyses.
• Optimization for Third-Generation Data: Designed to map long, error-prone reads from third-generation sequencing technologies efficiently.
• Gene Identification in Metagenomes: Supports detection of known genes within complex metagenomic assemblies through graph-based mapping.

Scientific Applications:

• Gene Finding: Enables discovery and mapping of genes by aligning sequences to graph-based genome assemblies.
• Haplotype Separation: Facilitates distinction of alternative haplotypes within assemblies by leveraging graph structure.
• Metagenomics Research: Permits identification of genes and sequences across diverse microbial communities using assembly graphs.

Methodology:

Uses graph-based genome assemblies (nodes and edges) and algorithms tailored to align long, diverged sequences and to handle errors typical of third-generation sequencing data.
