Hi, I have a set of genes with Refseq ids (ex. XM_020713141.1) and I want to convert it to EntrezID (ex. 101165603) for further analysis. I find similar question that said clusterProfiler is suitable for this purpose. [GeneBank accession 2 Entrez gene id ] However, I'd tried to find out Medaka (Oryzias latipes) annotation database in Bioconductor annotation packages because I use Medaka for research, there is only major species packages. Is there a way to access NCBI medaka annotation database to covert IDs? Or could you provide me some other method to solve this problem? I would be grateful if you could help me.
