pysradb

pysradb provides programmatic access to NCBI Sequence Read Archive (SRA) metadata and raw next-generation sequencing datasets, enabling systematic querying and retrieval for reproducible analyses.

Key Features:

• Programmatic querying: Enables scripted queries of SRA metadata to locate datasets and associated metadata entries.
• Metadata-driven retrieval: Utilizes the curated SRAdb metadata database to search and filter SRA records.
• Raw sequencing data retrieval: Supports retrieval and downloading of raw sequencing datasets from the SRA.
• Large-scale dataset handling: Facilitates systematic access to large volumes of next-generation sequencing data.

Scientific Applications:

• Dataset discovery and reanalysis: Locating and retrieving public next-generation sequencing datasets for reanalysis of experiments.
• Reproducibility and meta-analysis: Aggregating SRA metadata and raw data to reproduce published analyses and perform cross-study comparisons.
• Large-scale data acquisition for bioinformatics analyses: Collecting bulk sequencing datasets to support hypothesis testing and downstream computational workflows.

Methodology:

Interfaces with the SRAdb curated metadata database to execute queries that return SRA metadata entries and dataset identifiers enabling retrieval of raw sequencing data.
