ontoCAT: an R package for ontology traversal and search

N. Kurbatova, T. Adamusiak, P. Kurnosov, M. A. Swertz, M. Kapushesky
2011 Bioinformatics  
The ontoCAT package supports a number of traversal and search functions on a single ontology, as well as searching for ontology terms across multiple ontologies and in major ontology repositories.  ...  We present ontoCAT-an R package to access ontologies in widely used standard formats, stored locally in the filesystem or available online.  ...  INTRODUCTION The R package ontoCAT was created to support basic operations on ontologies: traversal and search, uniform access to ontologies in OWL (Lacy, 2005) and OBO (Barry et al., 2007) formats  ...

Methods for Determining the Genetic Causes of Rare Diseases

Daniel Greene, Apollo-University Of Cambridge Repository, Apollo-University Of Cambridge Repository, Ernest Turro, Sylvia Richardson, Willem Ouwehand
I developed a suite of software packages dubbed 'ontologyX' in order to simplify analysis and visualisation of such ontologically encoded data, and enable them to be incorporated into complex analysis  ...  It does so by evaluating support for a model under which the probability that a person carries rare alleles in a locus depends on the similarity between the person's ontologically encoded phenotype and  ...  Software for working with ontological data The ontoCAT R package enables simple querying and traversal of ontologies, but many of its key functions are slow and dependency on Java hinders its portability  ...
