Gene Ontology is a significant sub-set of Bioinformatical analysis on genes of varied living sources or genetic materials. It refers to assigning relevant biological terms to the genes and viewing the relationships in the form of interconnected graphs.
Gene Ontology is a term that comprises three broad biological aspects- cellular components, molecular functions, and biological processes. There are many gene ontology tools available that help in identifying the GO terms associated with a gene or protein.
Some of the best gene ontology tools are free to use as public web- browsers. Some are downloadable on local machines for offline usage.

5. GOnet
GOnet is a bioinformatics tool for interactive gene ontology analysis. It is an open-source web application that takes a list of genes and proteins as input and generates GO term annotation analysis for human or mouse data.
The tool is capable of producing convertible data formats and interactive visualization of the Gene Ontology results. Allows the users to explore genes and GO terms for the depiction of a natural hierarchy of the terms and retains relationships between genes and proteins.
The interactive output graph allows to re-arrange genes and GO term annotations to optimally represent the interpretation of discovered functional classification patterns. Depending on the number of nodes visualized, different layouts can be opted.
KEY FEATURES
- Input includes a list of genes and proteins from the specific organism
- Analysis of three domains can be obtained separately as an output graph
- The default output format is an Interactive graph, CSV, machine-readable text file also
- Supports multiple export options for downstream analysis
6. GOATOOLS
GOATOOLS Is a Python-based library that allows latest ontology and annotations for genes enrichment. It organises results for clarity and easier interpretation using GOATOOLS grouping methods.
It processes over and under-representation of certain gene ontology terms based on Fisher’s exact test. It includes multiple test corrections from stats models. It processes the obo-formatted file from the Gene Ontology website.
The data structure is a directed acyclic graph that allows easy traversing from leaf to root. Easily read the gene ontology association files such as GAF, GPAD, NCBIs gene2go file and id2gos formats. The GO terms can be grouped for easy viewing.
KEY FEATURES
- Identify ancestors or parents for a GO term with or without optional relationships
