New and Updated Online Tutorials for Textpresso and Gene Ontology

Comprehensive tutorials on the Gene Ontology and Textpresso databases enable researchers to quickly and effectively use these invaluable resources.

Seattle, WA (PRWEB) December 8, 2008 -- OpenHelix today announced the availability of an updated suite on the Gene Ontology (GO) database and a new tutorial on Textpresso. Gene Ontology is a consortium project developed to create a list of biologically relevent and carefully structured terms that can be shared among all sorts of bioinformatics resources. Textpresso is a customizable open source web tool, using GO ontologies, that allows you to text-mine the biological literature. In addition to the OpenHelix Controlled Vocabularies tutorial and others, these two tutorials give the researcher an excellent start to understanding and using gene ontologies.

The tutorial suites, available for single purchase or through a low-priced yearly subscription to all OpenHelix tutorials, contain a narrated, self-run, online tutorial, slides with full script, handouts and exercises. With the tutorials, researchers can quickly learn to effectively and efficiently use these resources. These tutorials will teach users:

Gene Ontology

  • how to understand the organization of the Gene Ontology hierarchies
  • how to search the AmiGO browser for terms, definitions, and annotated genes and gene products
  • how to begin with sequence data and find useful terms and definitions that may help to characterize your sequence of interest


  • how Textpresso works
  • the layout for all Textpresso sites
  • how to perform both basic and advanced searches
  • how to use Textpresso as an information retrieval and extraction tool

To find out more about these and other tutorial suites visit the OpenHelix Tutorial Catalog and OpenHelix or visit the OpenHelix Blog for up-to-date information on genomics.
