Read coverage is the number of sequencing reads aligned over each base. It is the main evidence that an assembled sequence is supported by data rather than being a mis-assembly, and a drop or a spike in coverage marks a place worth looking at closely. These tracks show coverage for the three long-read technologies used for this genome, and for the reads of the earlier zebra finch reference mapped onto the new assembly.
This collection holds the HiFi Coverage, ONT Coverage and CLR Coverage tracks. Each has its own description page with the details of how it was made, reachable from the track name in the browser or from the list below the configuration controls on this page.
The individual track description pages carry the download and intersection instructions for each annotation. The original files are on GenomeArk, in the bTaeGut7 annotations directory.

The assembly and all of these annotations were produced by the Vertebrate Genome Laboratory at The Rockefeller University and their collaborators, and released through GenomeArk. Thanks to Giulio Formenti and Erich D. Jarvis and their co-authors for making the data available before and after publication. The analysis code is at github.com/gf777/T2T-zebra-finch. This hub was assembled at UCSC from the IGV session distributed with the annotations, using hubtools.
