I am seeking to lift over gene IDs from rat to human, this is what I got:
library("biomaRt") human = useMart("ensembl", dataset = "hsapiens_gene_ensembl") rat = useMart("ensembl", dataset = "rnorvegicus_gene_ensembl") x = c("Tll1", "Tlx3") # gene list to lift over genesV2 = getLDS(attributes = c("mgi_symbol"), filters = "mgi_symbol", values = x , mart = rat, attributesL = c("hgnc_symbol"), martL = human, uniqueRows=T) genesV2
I found several entries for the lift over between mouse and human, but not rat and human. Hope that for people working good time with biomaRt, this could be easy to solve. I will keep on searching in the mean time.
thank you & best wishes
