h4CONCUR

h4CONCUR estimates codon counts from ribosome profiling (Ribo-seq) BAM-format aligned reads to generate site-specific codon usage profiles at the ribosomal E-, P-, and A-sites and their flanking regions for analysis of translation dynamics.

Key Features:

• Codon Count Estimation: Estimates codon usage by analyzing aligned Ribo-seq reads to calculate codon counts.
• Site-Specific Analysis: Assigns codon counts specifically to ribosomal E-, P-, and A-sites and their flanking regions.
• Input Format: Accepts aligned reads in BAM format as input.
• Output Generation: Produces detailed reports of codon usage and counts for downstream analysis.
• Implementation and Requirements: Implemented in Perl and requires Perl and bedtools, with compatibility for Linux and macOS.

Scientific Applications:

• Translational Efficiency Studies: Enables analysis of how codon usage influences translation speed and accuracy using Ribo-seq data.
• Gene Expression Analysis: Supports investigation of codon bias effects on gene expression levels.
• Evolutionary Biology Research: Facilitates detection of codon usage patterns indicative of evolutionary pressures and species-specific translational mechanisms.

Methodology:

Processes Ribo-seq data by accepting BAM-format aligned reads, estimating codon counts at ribosomal E-, P-, and A-sites and their flanking regions, and generating detailed codon usage reports.
