picard_samtofastq

picard_samtofastq converts SAM-format alignments into FASTQ-format reads to recover raw sequencing reads and base quality scores for downstream analyses such as variant calling, quality control, metagenomics, and phylogenetics.

Key Features:

• Format Conversion: Converts SAM files containing aligned sequencing reads into standardized FASTQ files containing sequences and quality scores.
• Integration with Galaxy: Operates within the Galaxy platform to be used in Galaxy-based workflows.
• Execution Engine: Executes using Galaxy's execution engine and can utilize computational resources on the Institut Pasteur cluster.
• API and Library Support: Supports automation and communication via the Galaxy API and the Bioblend library.

Scientific Applications:

• Metagenomic Analysis: Prepares aligned sequencing data for metagenomic pipelines by producing raw-read FASTQ inputs.
• Phylogenetic Studies: Provides FASTQ reads required for downstream phylogenetic inference workflows such as next-generation phylogenetic tools.
• Variant Calling and Quality Control: Supplies raw sequencing reads and quality scores needed for variant calling pipelines and sequence quality assessment.

Methodology:

Extracts read sequences and their corresponding base quality scores from SAM records and writes them in FASTQ format.
