High-throughput (or, next-generation) sequencing data analysis requires a specialized biological and computational skillset. Scientists are required to work with large and complex files, program pipelines, use powerful computer hardware, and interpret results in a statistical context. While some analytical frameworks can be quite involved, several core steps are repeated among analyses. This webinar will describe the general workflow of a typical bioinformatic analysis, identifying variants from high-throughput sequencing data, starting from first principles.
