Essentially, the gene_id on the differential expression excel list (TIMP1 instead of ENSG00000102265). I prefer Ensembl, and the annotation would be the GTF/GFF file housed in the same FTP server with the genome sequence. It could be useful when one could label the heatmap with the gene name in the case of study that deals with individual gene but it is becoming less and less indispensable when everything happens from server to server.
To annotate genes with key of one's choice at the data visualization state, plainly it is just a matter of matching the the gene_id with the designated gene name in the annotation data frame, and that means it is about data manipulation in R. I will go into details in the later section.
