I have to convert the gene names in my scRNA-seq data into ensembl IDs for downstream analyses. I used biomaRt package which converted some of the gene names:
library(biomaRt) ensembl = useMart("ensembl",dataset="hsapiens_gene_ensembl") biomart_hgnc <- getBM(attributes = c("hgnc_symbol", "ensembl_gene_id"), filters = "hgnc_symbol", values = rownames(LeeCRCtumor), bmHeader = T, mart = ensemble)
However, it returns several ensemble ids for one gene like here:
should I specify the gene location/chromosome in this case?
