trackDb.txt file used in
both Track Hubs and Assembly Hubs; however, this page does not describe the settings unique to
Assembly Hubs. Track Hubs can display novel genomes, through a type of hub called an
Assembly Hub.
The genomes.txt file for an Assembly Hub involves
many additional settings not described on this page, such as
twoBitPath and
defaultPos to
identify the location of the sequence for the novel assembly and what default position to
display. The genomes.txt file in Assembly Hubs also requires display information
such as organism,
scientificName,
description,
+orderKey,
and htmlPath to
label the novel assembly on the gateway page. A special groups setting in Assembly Hubs points to a separate text
document that defines track groups under the main image (such as the first "Mapping and
Sequencing" group found on almost all Browsers). Read the "Create the genomes.txt file" section
of the Track Hub User Guide for more information, and see examples in the Quick Start Guide to Assembly Hubs.
