scrnaseq - What are RIKEN genes? - Bioinformatics Stack Exchange There are some specific genes with name ending with suffix 'Rik' (e g 0610005C13Rik or 0610007C21Rik) Searching online I found that they are from RIKEN project However, they are different in some respects (e g antisense lncRNA gene, or mouse 0610007C21RIK Adenovirus)
Converting Gene Symbol to Ensembl ID in R I tried several R packages (mygene, org Hs eg db, biomaRt, EnsDb Hsapiens v79) to convert Ensembl gene to gene symbol, and found that the EnsDb Hsapiens v79 package gene database provides the best conversion quality (in terms of being able to convert most of Ensembl gene to gene symbol)
