Hi all,
I frequently use R biomaRt for querying ensembl. Over the weekend I
experienced a problem with biomaRt. whatever I query I get
> library(biomaRt)
> ensembl=useMart("ensembl")
> listDatasets(ensembl)
> ens_sap=useMart("ensembl", dataset="hsapiens_gene_ensembl")
> attr_sap=listAttributes(ens_sap)
> filter_sap=listFilters(ens_sap)
>
> getBM(attributes="ensembl_gene_id", filters="hgnc_symbol",
values="FUS",
>mart=ens_sap)
Error in getBM(attributes = "ensembl_gene_id", filters =
"hgnc_symbol", :
Query ERROR: caught BioMart::Exception::Database: Could not connect
to mysql
database ensembl_mart_61: DBI
connect('database=ensembl_mart_61;host=dcc-qa-
db.oicr.on.ca;port=3306','bm_web',...)

>values="NM_001134363", mart=ens_sap)
I asked ensembl help desk and they advised me to use directly ensembl
mart through this:
>library(biomaRt)
>ensembl=useMart("ENSEMBL_MART_ENSEMBL", host="www.ensembl.org")
>dataset="hsapiens_gene_ensembl"
>ensembl=useDataset(dataset, mart=ensembl)
..however when I try this command I get the following:
> ensembl=useMart("ENSEMBL_MART_ENSEMBL", host="www.ensembl.org")
Space required after the Public Identifier
SystemLiteral " or ' expected
SYSTEM or PUBLIC, the URI is missing
Error: 1: Space required after the Public Identifier
2: SystemLiteral " or ' expected
3: SYSTEM or PUBLIC, the URI is missing
Does anyone know how to fix this problem?
Thanks a lot,
Stefanie
