M-GCAT 2.0 beta

M-GCAT 2.0 beta performs anchor-based multiple genome comparison to rapidly identify and align highly conserved genomic regions across multiple closely related genomes for comparative and evolutionary analyses.

Key Features:

• Compressed suffix graph anchoring: Uses a compressed suffix graph to implement anchor-based multiple genome comparison and to construct multiple genome alignment frameworks.
• High-throughput comparison: Compares conserved regions across up to 20 closely related bacterial species in minutes and can handle larger datasets (e.g., ~90 genomes, including 75 cloned genomes derived from 15 published enterobacterial genomes) within about an hour.
• Optimized for closely related species: Targets detection and alignment of highly conserved regions among closely related genomes to support fine-scale evolutionary analysis.

Scientific Applications:

• Evolutionary biology: Rapid identification of conserved genomic regions to study evolutionary processes among closely related species.
• Microbial genetics and comparative genomics: Comparative analysis of bacterial genomes, including enterobacterial datasets, to investigate gene conservation and divergence.
• Large-scale genomic studies: Processing of tens to scores of genomes for large-scale comparative genomic investigations.

Methodology:

Performs anchor-based multiple genome comparison using a compressed suffix graph to build multiple genome alignment frameworks.
