Have you ever wondered what we mean by "track" or what the difference is between "haplotype" and "fix" sequences? We are pleased to announce the release of a new Genome Browser Glossary page. It provides a guide to the tools and features of the Genome Browser as well as the terminology used across the site.
The glossary covers a wide range of topics including genome assemblies and nomenclature, core tools, browser interface elements and interactions, tracks and display modes, user data features, common data formats, genome browser data and annotations, and technical terms. For example, it describes the various -interface buttons and interactions available you from the main genome browser +interface buttons and interactions available to you from the main genome browser graphic, such as the ability to drag-and-reorder tracks or drag-and-zoom. Contact us if there are terms you'd like to see added.
The configuration page for superTracks has been updated with new controls for managing track visibility. SuperTracks are containers that group a variety of track types, including composite tracks, and support two levels of hierarchy for complex nesting (e.g., superTrack > composite > subtrack).
