[BioC] BiomaRt error: server down?

Wed Feb 22 12:27:11 CET 2012

Hi Lisa,
You can try doing the same from Ensembl bioMart http://www.ensembl.org/biomart/martview/c99651c657859e8078d6513f6b136815
And selecting uniprot Swissport/TrEMBL under 'External'.

Subject: [BioC] BiomaRt error: server down?

Hallo,

I'm trying to map Uniprot accessions to Ensembl protein IDs using the biomaRt library in bioconductor.  This has worked in the past, but I'm getting an error today.  Is the server down?  Is there anywhere/anyhow I can check whether the server is down?

MWE and errors follow:

=============================
library(biomaRt)

human.ensembl <- useMart("ensembl", dataset = "hsapiens_gene_ensembl") uniprot.list <- c( "Q09666" )

uniprot2ensembl <- getBM(
  attributes = c( "uniprot_swissprot_accession","ensembl_peptide_id" ),
  filters    = "uniprot_swissprot_accession",
  values     = uniprot.list,
  mart       = human.ensembl )

=============================

  The query to the BioMart webservice returned an invalid result: the number of columns in the result table does not equal the number of attributes in the query. Please report this to the mailing list.
