Simulate ancient DNA deamination damage on paired-end FASTQ files

simulate_damage

simulate_damage is a command-line tool that simulates ancient DNA (aDNA) deamination damage in paired-end FASTQ files. It introduces realistic C→T and G→A transitions at read ends and internally, allowing researchers to test pipelines under damage conditions typical of ancient samples.

Features

• Supports .fastq and .fastq.gz
• Handles paired-end reads automatically
• Allows custom damage rates for 5′ and internal C→T (R1) and G→A (R2)
• Keeps original read qualities and structure
• Fully scriptable or callable via CLI
