Description

An object of class "Anno" that contains associations between Disease Ontology terms and SCOP domain families (fa). This data is prepared based on the dcGO database (see http://supfam.org/SUPERFAMILY/dcGO/).

Usage

data(SCOP.fa2DO)

Value

an object of class Anno. It has slots for "annoData", "termData" and "domainData":

• annoData: a sparse matrix of domains X terms
• termData: variables describing ontology terms (i.e. columns in annoData), including: "ID" (i.e. term ID), "Name" (i.e. term Names), "Namespace" (i.e. term Namespace), and "Distance" (i.e. term Distance to the ontology root)
• domainData: variables describing domains (i.e. rows in annoData), including: "id" for SCOP sunid, and "level" for SCOP level, "description" for SCOP description
