Download FastQC – Quality Control Tool for High-Throughput Sequencing Data

FastQC is a widely-used quality control tool for high-throughput sequencing data. Developed by the Babraham Institute, it provides a comprehensive set of analyses to rapidly assess the quality of raw sequencing reads from platforms such as Illumina, Oxford Nanopore, PacBio, and others. FastQC produces detailed HTML reports that highlight potential issues in sequencing data before downstream analysis.

Each FastQC report includes multiple quality metrics including per-base sequence quality scores, GC content distribution, sequence duplication levels, adapter contamination detection, and overrepresented sequence analysis. These metrics help bioinformaticians identify whether data requires trimming, filtering, or additional preprocessing before alignment or assembly.

FastQC runs as a standalone Java application with both a graphical interface for interactive analysis and a command-line mode suitable for batch processing and integration into bioinformatics pipelines. It is one of the first tools run in virtually every next-generation sequencing (NGS) workflow.

Key Features

• Per-base and per-sequence quality score analysis with interactive graphs.
• GC content distribution check to detect contamination or library bias.
• Sequence duplication level analysis to identify PCR artifacts.
• Adapter content detection for common Illumina and other sequencing adapters.
• Overrepresented sequence identification for contamination screening.
• Batch processing via command-line for integration into NGS pipelines.
• Generates self-contained HTML reports and ZIP archives for easy sharing.

How to Install
