CLARC

CLARC improves pangenome analyses by condensing accessory clusters of orthologous groups (COGs) using functional annotation and linkage information, consolidating orthologous groups into more practical units of selection.

Key Features:

• Accessory COG Condensation: CLARC reduces accessory gene estimates by >30% through refinement of COG definitions.
• Functional Annotation Integration: CLARC incorporates functional annotation to inform ortholog group consolidation.
• Linkage Information Utilization: CLARC uses gene linkage patterns to refine COG classifications and identify true orthologs.
• Cross-Species Applicability: CLARC is effective across different bacterial species for comparative genomics analyses.

Scientific Applications:

• Bacterial Pangenome Analysis: CLARC classifies genes into core and accessory COGs while correcting misclassifications from strict sequence identity cutoffs.
• Evolutionary Prediction: CLARC improves evolutionary predictions based on accessory gene frequencies in bacterial populations.
• Large-Scale Genome Studies: CLARC has been applied to analyze 8000+ Streptococcus pneumoniae genomes for population-level genetic studies.
• Bacterial Evolution Research: CLARC aids genetic studies across diverse bacterial populations by refining ortholog definitions.

Methodology:

CLARC uses functional annotation and linkage information to condense accessory COGs and consolidate orthologous groups.
