Hi Javier. You might find the following exchange between myself and the ENSEMBL help desk last week useful. First my email: Using biomaRt through R to try and retrieve the 3'UTR start and end for a set of transcript ids I get the following error. V1 1 Query ERROR: caught BioMart::Exception::Usage: Attribute 3utr_start NOT FOUND Error in getBM(attributes = c("ensembl_transcript_id", "sequence_3utr_start"), : Number of columns in the query result doesn't equal number of attributes in query. This is probably an internal error, please report. Could you tell me the easiest way to get hold of the 3'utr coordinates through the web interface please? Thanks Iain And the reply: Hello Iain, Currently these attributes are not available from BioMart. They have been dropped when we moved to an automated Mart building process a few months ago. However, as many people have asked for these attributes, they have been added again to our v52 release which, if everything goes according to plan, should go live coming week. My apologies for any inconvenience caused. Hope that helps.
