Holly, You can find out the current version by using the following two lines of code. mart1 = useMart(biomart="ensembl") listDatasets(mart1) 51 mmusculus_gene_ensembl Mus musculus genes (GRCm38) GRCm38 Here is how you obtain mm10 TSS. mm10 = useMart(biomart="ensembl", datset="mmusculus_gene_ensembl") TSS.mouse.mm10 = getAnnotation(mart=mm10, featureType="TSS") For detailed information on how to useMart for different versions or genomes, please type help(useMart) and help(listDatasets). Please keep the thread in the bioconductor list for others to input/benefit. Thanks!

I want to use mm10 assembly, and found the tutorial as following. However, it is not clear how to decide the mm9 and mm10 assembly when grabbing TSS from biomaRt. Could you please clarify it? Thanks. library(biomaRt) ensmart = useMart(biomart="ensembl", dataset="mmusculus_genes_ensembl") TSS.mouse.NCBIM37 = getAnnotation(mart=ensmart, featureType="TSS") Session <- sessionInfo() Holly [[alternative HTML version deleted]]
