The versatile open source genome analysis software

[Genome Annotation]

The GenomeTools genome analysis system is a free collection of bioinformatics tools (in the realm of genome informatics) combined into a single binary named gt. It is based on a C library named “libgenometools” which consists of several modules.

If you are interested in gene prediction, have a look at GenomeThreader.


GenomeTools has been designed to run on every POSIX compliant UNIX system — for example Linux or macOS. A reduced Windows version is also available. Please report problems to our issue tracker.
