Summary

Steven Wingett, a bioinformatician at the MRC Laboratory of Molecular Biology, presents an introductory talk on data pipelines for next-generation sequencing (NGS) analysis. He begins by explaining the basics of NGS, including the Illumina sequencing technology, the concept of massively parallel sequencing, and the different types of sequencing (e.g., single-end vs. paired-end, bulk vs. single-cell). He describes the output of sequencing instruments, focusing on FASTQ files, their structure, and the importance of quality scores. He emphasizes the critical need for proper data storage, including checking MD5 sums to ensure data integrity. The core of the talk introduces bioinformatics pipelines, specifically Nextflow and the nf-core suite, as tools to manage and automate the analysis of large NGS datasets. He highlights the importance of quality control checks at each stage of the pipeline. The talk is aimed at newcomers to the field, providing a practical overview of the initial steps in NGS data analysis.
