picard_arrg

picard_arrg modifies read group metadata in BAM and SAM files (Picard "Add or Replace Read Groups") to ensure accurate annotation of sequencing reads for downstream genomic analyses.

Key Features:

• Metadata Management: Adds or replaces read groups in BAM/SAM files, including fields that describe sequencing platform, library, and experimental conditions.
• Data Integrity: Updates and standardizes read group information to maintain consistency across samples and support downstream analyses such as variant calling and differential expression.

Scientific Applications:

• Biomedical Research: Manages sequencing data generated by next-generation sequencing technologies used in biomedical studies.
• Large-Scale Analyses: Ensures consistent read group metadata across multiple samples or experiments in large-scale genomics projects.

Methodology:

Parses input BAM/SAM files to identify existing read groups and allows specification or modification of read group attributes to re-annotate sequence reads.
