Description

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

Usage

data(SCOP.fa2GOBP)

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
