Convert Gene IDs — convertGeneIDs • singleCellTK

Convert the gene IDs in a SingleCellExperiment object using Bioconductor org.*.eg.db data packages. Because annotation databases do not have a 1:1 relationship, this tool removes rows with no corresponding annotation in your desired annotation, and remove any duplicate annotations after conversion.

convertGeneIDs(inSCE, inSymbol, outSymbol, database = "org.Hs.eg.db")

Arguments

inSCE: Input SCtkExperiment object. Required
inSymbol: The input symbol type
outSymbol: The output symbol type
database: The org.*.eg.db database to use. The default is org.Hs.eg.db

Value

A SCtkExperiment with converted gene IDs.

Examples

if(requireNamespace("org.Mm.eg.db", quietly = TRUE)) {
  #convert mouse gene symbols to ensembl IDs
  library("org.Mm.eg.db")
  sample(rownames(mouseBrainSubsetSCE), 50)
  mouseBrainSubsetSymbol <- convertGeneIDs(inSCE = mouseBrainSubsetSCE,
                                           inSymbol = "SYMBOL",
                                           outSymbol = "ENSEMBL",
                                           database = "org.Mm.eg.db")
  sample(rownames(mouseBrainSubsetSymbol), 50)
