useOneFile on for hubs with only one genome
This page focuses on the settings found in the trackDb.txt file;
however, all hubs must include a top-level hub.txt.
If your hub is only displaying one genome, there is a way to put the genomes.txt and
trackDb.txt
all into one file. Read about the special useOneFile on setting to
allow all a hub to exist in one file. Load a working example here.
+Hubs also support the use of include +statements, allowing one to insert a file containing a set of trackDb +stanzas into a primary trackDb. Use this when you have the same track across +several assemblies, or several large, complex tracks. +
This page focuses on the settings found in the 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,
