While creating an object for topGO as :
sampleGOdata <- new("topGOdata", description = "Simple session", ontology = "BP", allGenes = P_values, geneSel = topDiffGenes, nodeSize = 10, annot = annFUN.db, affyLib = affyLib)
what if there is no annotation database available for that particular organism in bioconductor?
Can someone tell me if there is any alternative available to use instead of the annotation databases of affylib(affyLib = affyLib).
Any guidance will be appreciated.
