Hi Julie I am using ChIPpeakAnno for my data. The annotation data I would like to use Zebrafish but Zv9, though annotated data package has TSS.zebrafish.Zv8. I downloaded the "GTF" file for Zv9 but I am unable to convert it into Ranged data using GFF2RangedData function since it accepts GFF file. Therefore, I am trying to make custom annotation using the following code. " # create a biomart object and select a mart to use ensembl <- useDataset("drerio_gene_ensembl", mart=useMart("ensembl")) # what kind of attributes can we retrieve? listAttributes(ensembl) # set the properties to extract props <- c("ensembl_gene_id", "external_gene_id", "transcript_biotype", "chromosome_name", "start_position", "end_position", "strand") # get the information genes <- getBM(attributes=props, mart=ensembl) # create a RangedData object with my custom annotations myCustomAnno <- RangedData(IRanges(start=genes[,"start_position"], end=genes[,"end_position"], names=genes[,"ensembl_gene_id"]), space=genes[,"chromosome_name"], strand=genes[,"strand"]) " But I am getting following error: "Error in `rownames<-`(`*tmp*`, value = c("ENSDARG00000085528", "ENSDARG00000087771", : duplicate rownames not allowed" I am unable to proceed ahead, also I very new in using this package. Could you suggest a solution.

Neha, Please use getAnnotation function in ChIPpeakAnno package to obtain the annotation data you need. For detailed information on how to use getAnnotation, please type help(getAnnotation) and let me know if this works for you. Thanks!
