For a given gene, I wanted to find which transcripts in ensembl are labelled 'Protein coding', which are labelled 'retained intron', etc.

I was using :

library(Biostrings) ## dna to rna
ensembl = useMart("ensembl", dataset=


    gb <- getBM(attributes=c("ensembl_transcript_id","transcript_start","transcript_end","ensembl_exon_id","exon_chrom_start","exon_chrom_end","strand","chromosome_name"),
                filters = "ensembl_gene_id", values=ensembl_id, mart=ensembl)   


but this doesn't give me the annotation for the various transcripts. Is there a way that I can get the annotations?

Dear Brian,

You can use the "Gene type" filter (called "biotype" in biomaRt) and the "gene_biotype" attribute to get this information, the following should give you all the Ensembl "protein_coding" genes:

gb <- getBM(attributes=c("ensembl_transcript_id","transcript_start","transcript_end","ensembl_exon_id","exon_chrom_start","exon_chrom_end","strand","chromosome_name","gene_biotype"),filters = c("ensembl_gene_id","biotype"), values=list(ensembl_id,"protein_coding"), mart=ensembl)

I am afraid you won't find "retained intron" in the "Gene type" filter as this type can only be found for transcript annotation (it can apply to both coding and non coding genes) but you can add the "transcript_biotype" attribute to your query and then post process the gb object:

gb <- getBM(attributes=c("ensembl_transcript_id","transcript_start","transcript_end","ensembl_exon_id","exon_chrom_start","exon_chrom_end","strand","chromosome_name","transcript_biotype"),filters ="ensembl_gene_id", values=ensembl_id, mart=ensembl)

To make things easier we are planning to add a "Transcript type" filter in our next Ensembl release (e!78).

Hope this helps,

Dear Brian,

1) The current version used by default by BiomaRt is GRCh38 (Ensembl release 77 on

We have created an Ensembl GRCh37 archive website accessible through the following URL:

You can access this archive through BiomaRt by setting up a different host in the useMart function:

grch37 = useMart(biomart="ENSEMBL_MART_ENSEMBL", host="", path="/biomart/martservice", dataset="hsapiens_gene_ensembl")

2) You can use the "listDatasets" function on your "ensembl" object to get the assembly version of all the Ensembl mart species:

Thanks Thomas! That works.


1. Is the current version of BiomaRt mapped to GRCh37 or GRCh38?

2. For the future, is there any command line tool in bioconductor that can tell me which version (37 or 38?)
