countreadgcpercent

countreadgcpercent calculates the GC content percentage for each DNA read aligned to a reference genome to quantify per-read guanine (G) and cytosine (C) composition in next-generation sequencing (NGS) datasets.

Key Features:

• GC Content Calculation: Determines the percentage of guanine (G) and cytosine (C) bases in each DNA read aligned to a reference genome.
• Reference-aware per-read analysis: Produces per-read GC metrics in the context of reads aligned to a reference genome.
• Integration with Galaxy Project: Implements execution within the Galaxy platform infrastructure.
• Scalability: Processes large NGS datasets to compute GC percentages across many reads in batch.

Scientific Applications:

• Genomic Characterization: Profiles per-read GC content to inform analyses of chromatin structure and gene regulation.
• Comparative Genomics: Compares GC content distributions across species or strains for evolutionary and diversity studies.
• Quality Control: Assesses GC content distributions to detect biases introduced during library preparation or sequencing.

Methodology:

Calculates per-read GC percentage by counting guanine (G) and cytosine (C) bases in DNA reads aligned to a reference genome from NGS datasets.
