Mouse gene to human gene

musGenes <- c("Hmmr", "Tlx3", "Cpeb4")
# Basic function to convert mouse to human gene names
convertMouseGeneList <- function(x){
require("biomaRt")
human = useMart("ensembl", dataset = "hsapiens_gene_ensembl")
mouse = useMart("ensembl", dataset = "mmusculus_gene_ensembl")

humanx <- unique(genesV2[, 2])
# Print the first 6 genes found to the screen
print(head(humanx))
return(humanx)
}

Human gene to mouse gene

# Basic function to convert human to mouse gene names

humanx <- unique(genesV2[, 2])
# Print the first 6 genes found to the screen
print(head(humanx))
return(humanx)
}
genes <- convertMouseGeneList(humGenes)
