CLARITY CLARITY is a tool and method for the storage and comparison of data with numeric and set membership components. It is specifically geared toward timecourse microarray data, which is used to study the activity of genes across time. By using data that has been redescribed into Gene Ontology (GO) terms, and summarizing the regulation of these terms across time using characters (together forming sequences) we are able to use standard DNA alignment techniques with these sequences. The Gene Ontology (GO), is a controlled vocabulary used to aid the description of genes and gene product attributes in a variety of organisms. There are three different ontologies that describe molecular functions, biological processes, and cellular components. Requirements: CLARITY Database -- which requires MySQL. Lispworks Enterprise Edition 4.2 or higher -- this restriction will be removed soon by making sure that the MySQL connection works on the freely available CL-SQL.
