Poretools

Poretools analyzes nanopore sequencing data from Oxford Nanopore Technologies' MinION by operating on native FAST5 (HDF5) files to enable exploration, quality control, format conversion, and downstream analysis of event- and sequence-level data.

Key Features:

• Direct FAST5 (HDF5) support: Reads and processes native FAST5 files produced by Oxford Nanopore Technologies' MinION.
• Format conversion utilities: Converts data between FAST5 and other bioinformatics formats to enhance interoperability with downstream tools.
• Data exploration and visualization: Produces graphical representations and detailed statistical summaries of sequencing and event-level data.
• Quality control: Generates metrics and summaries to assess nanopore sequencing run performance.
• Downstream analysis support: Prepares and exports read- and event-level data for further computational analyses.
• Streaming event data analysis: Supports analysis of real-time, streaming event data from the MinION device.
• Raw data preservation: Operates without required intermediate conversions to preserve raw signal and metadata integrity.

Scientific Applications:

• Nanopore run quality assessment: Evaluate sequencing performance and run-level metrics for MinION datasets.
• Signal- and read-level exploration: Inspect event-level signals and read-level summaries for experimental interpretation.
• Data preparation for downstream workflows: Convert and export native data to formats usable by other bioinformatics analyses.
• Real-time monitoring of sequencing: Analyze streaming event data for immediate assessment during MinION runs.

Methodology:

Directly reads native FAST5 (HDF5) files, performs format conversions, computes statistical summaries, and generates visualizations of event- and read-level data.
