The Ensembl project (www.ensembl.org) offers integrated genome, variation, gene regulation and comparative genomics data of mainly vertebrate genomes on an open access web browser platform. This webinar will introduce you to the analysis of Linkage Disequilibrium (LD) between variants with Ensembl. We will look at different ways to explore and visualise LD in the Ensembl genome browser website. We will discuss the LD Calculator tool (https://www.ensembl.org/Homo_sapiens/...) and show how to use it.
