[ensembl-dev] biomaRt issue

[Thomas Maurel]

Dear Julien,

Yes, this is the right place to post this since you are querying the Ensembl marts on ensembl.org ;-)
There is nothing wrong with your code, I’ve just tried your query and got the result in few minutes:
> library("biomaRt")
> ensembl71 <- useMart(host='apr2013.archive.ensembl.org', biomart='ENSEMBL_MART_ENSEMBL', dataset='hsapiens_gene_ensembl')
> GO <- getBM(attributes=c(‘go_id', 'name_1006', 'namespace_1003'), mart = ensembl71)
> head(GO)
       go_id                                    name_1006     namespace_1003
1 GO:0007186 G-protein coupled receptor signaling pathway biological_process
2 GO:0016021                         integral to membrane cellular_component
3 GO:0005886                              plasma membrane cellular_component
4 GO:0004930          G-protein coupled receptor activity molecular_function
5 GO:0004984                  olfactory receptor activity molecular_function
6 GO:0008150                           biological_process biological_process

It could be that our website our your internet connection had a glitch. Could you please try again?
You could also try to update the BiomaRt package to the current 2.20 version (http://www.bioconductor.org/packages/release/bioc/html/biomaRt.html <http://www.bioconductor.org/packages/release/bioc/html/biomaRt.html>) and update your R software version.
It’s also good practice to refrain yourself from running full genome queries with BioMart, an easy way around this is to us filters to break down your query in smaller pieces (e.g: to filter on chromosome names).

Hope this helps,
Regards,
Thomas
