I have a normalized data file containing gene symbols as first column followed by various samples (normalized data). I was looking to extract the Ensembl IDs corresponding to the gene symbols. Basically, I would like to have both gene symbols and Ensembl IDs in the data file for further downstream analysis. Please assist me with this.
gene_symbol Sample_1 Sample_2
gene_symbol Ensembl ID Sample_1 Sample_2
