Tracks
A track is a very fundamental building block for NGS analysis in the CLC Genomics Workbench. The idea behind tracks is to provide a unified framework for the visualization, comparison and analysis of genome-scale studies such as whole-genome sequencing or exome resequencing projects and a variety of different -Seq data (i.e. ChIP-Seq, DNAse-Seq).24.1
In tracks, all information is tied to genomic positions - so a reference genome provides a central coordinate-system such that different datasets can be seen and analysed together. Different kinds of tracks exist: a reference genome sequence (
), a set of genes (
), a coverage graph (
), a read mapping (
) or variants from variant calling (
). This chapter explains how to visualize tracks, how to retrieve reference data and finally how to perform generic comparisons between tracks. For comparison tools specific to resequencing and variants, please see Resequencing.
