The simpliest way to add a description to your track is to add an html declaration in each of your track stanzas to define the location of the html. For instance, adding html would define this page as your track description page.


The description should help users understand the content of the tracks and reviews the concepts or analysis represented. Often a publication abstract can provide a good description.

Example text: This track represents the Ensembl Regulatory Annotation of regional function and activity in each of 17 human cell types. The Ensembl Regulatory Build provides a genome-wide set of regions that are likely to be involved in gene regulation. These regions are classified into six functional types (see below).

Display Conventions and Configuration

This section describes track configuration controls, or any special display conventions such as the meaning of different colors in your tracks.

Example text: The colours used for each of the functional classification follow the agreed ENCODE segmentation standard:
