cai

cai calculates the codon adaptation index (CAI) for coding sequences to measure relative codon adaptiveness against a reference set and infer potential gene expression and translational efficiency.

Key Features:

• Codon Adaptation Index calculation: Computes the CAI by comparing codon frequencies in a query coding sequence to a user-supplied reference set.
• EMBOSS integration: Operates as part of the EMBOSS suite to enable usage within EMBOSS-based computational workflows.
• Extensible C libraries: Built on EMBOSS's extensible C programming libraries to support integration and high-performance execution.
• ACD-based configuration: Supports Application Configuration Description (ACD) files to adjust application behavior and parameters.

Scientific Applications:

• Gene expression analysis: Infers potential gene expression levels by assessing codon usage bias relative to highly expressed reference genes.
• Translational efficiency and evolutionary studies: Assesses translational efficiency and examines codon usage patterns for evolutionary analyses and synthetic biology design.

Methodology:

Analyzes coding sequences to determine per-codon frequencies relative to a reference set (typically derived from highly expressed genes) and calculates an index value that reflects codon adaptiveness.
