Hi Peter, I think its not possible to annotate DERs with gene symbols using the MEDIPS.annotate function. I recommend to use other tools available in R/Bioconductor for annotating genomic coordinates, such as ChIPpeakAnno, I have no experience with it but I think it can do the job?

I've tried things like; annotation='HGNC-SYMBOL' or 'Symbol' both upper and lower case but don't seem to work. I can covert the IDs via biomart but this doesn't retain order or allow for multiple entries of the same ensemble ID.
