TRGT is a tool for targeted genotyping of tandem repeats from PacBio HiFi data. In addition to the basic size genotyping, TRGT profiles sequence composition, mosaicism, and CpG methylation of each analyzed repeat and visualization of reads overlapping the repeats.

Version information

Current version: 5.0.0.

For a complete changelog, see the changelog or the git history.

Active development warning

Please note that TRGT is still under active development. We anticipate some changes to the input and output file formats of TRGT.

Availability

TRGT Linux binary is available here

Repeat catalogs

In order to use TRGT, you need to specify which repeats you want it to analyze. Here are some repeat catalogs that you can use.

STRchive is a high-quality catalog containing definitions of known pathogenic repeats. It is described here.
"Adotto" genome-wide repeat catalog described in the original TRGT paper and here.
Genome-wide repeat catalog containing isolated tandem repeats and variation clusters described here.
Catalog of pathogenic repeats originally distributed with TRGT has been deprecated; please use STRchive.

Joint analysis of multiple samples

TRGT outputs VCFs containing repeat alleles from each region in the repeat catalog. To facilitate analysis of repeats across multiple samples, VCFs can be either merged into a multi-sample VCF using the merge sub-command or converted into a database using the TDB tool (formerly called TRGTdb). TDB offers many advantages over multi-sample VCFs, including simpler data extraction, support for queries, and reduced file sizes.
