Description

Protein Sequence Similarity Calculation based on Gene Ontology (GO) Similarity

Usage

calcParProtGOSim(golist, type = c("go", "gene"), ont = "MF",
  organism = "human", measure = "Resnik", combine = "BMA")

Arguments

golist	A character vector, each component contains a character vector of GO terms or one Entrez Gene ID.
type	Input type of golist, 'go' for GO Terms, 'gene' for gene ID.
ont	Default is 'MF', could be one of 'MF', 'BP', or 'CC' subontologies.
organism	Default is 'human', could be one of 'anopheles', 'arabidopsis', 'bovine', 'canine', 'chicken', 'chimp', 'coelicolor', 'ecolik12', 'ecsakai', 'fly', 'human', 'malaria', 'mouse', 'pig', 'rat', 'rhesus', 'worm', 'xenopus', 'yeast' or 'zebrafish'.
measure	Default is 'Resnik', could be one of 'Resnik', 'Lin', 'Rel', 'Jiang' or 'Wang'.
combine	Default is 'BMA', could be one of 'max', 'average', 'rcmax' or 'BMA' for combining semantic similarity scores of multiple GO terms associated with protein.

Details

Examples

# by GO Terms
go1 = c('GO:0005215', 'GO:0005488', 'GO:0005515', 'GO:0005625', 'GO:0005802', 'GO:0005905')  # AP4B1
go2 = c('GO:0005515', 'GO:0005634', 'GO:0005681', 'GO:0008380', 'GO:0031202')  # BCAS2
go3 = c('GO:0003735', 'GO:0005622', 'GO:0005840', 'GO:0006412')  # PDE4DIP
glist = list(go1, go2, go3)
gsimmat1 = calcParProtGOSim(glist, type = 'go', ont = 'CC')
print(gsimmat1)

# by Entrez gene id
genelist = list(c('150', '151', '152', '1814', '1815', '1816'))
gsimmat2 = calcParProtGOSim(genelist, type = 'gene')
print(gsimmat2)
