Hi all,
I am using biomaRt to annotate Ensembl IDs, from Mus musculus genome, version 80.
As the current version is 81, I am using an archived version, here is how I proceed:
# connecting to the right version of Ensembl, this works well:
my_mart <- useMart(host="may2015.archive.ensembl.org", biomart="ENSEMBL_MART_ENSEMBL", dataset="mmusculus_gene_ensembl")
# mapping Ensembl IDs to retrieve more detailed annotation:
getBM(attributes=c("ensembl_gene_id", "chromosome_name", "start_position", "end_position", "strand", "description", "external_gene_name"), filters ="ensembl_gene_id", values = "ENSMUSG00000071528", mart=my_mart)
Here I get the following error:
"
Error in getBM(attributes = c("ensembl_gene_id", "chromosome_name", "start_position", :
Query ERROR: caught BioMart::Exception::Database: Could not connect to mysql database ensembl_mart_80: DBI connect('database=ensembl_mart_80;host=ensdb-web-13;port=5314','ensro',...) failed: Can't connect to MySQL server on 'ensdb-web-13' (110) at /ensemblweb/archive/www_80/biomart-perl/lib/BioMart/Configuration/DBLocation.pm line 98.
"
Trying the same thing with the current version (81), I do not get this error:
my_mart2 <- useMart(host="www.ensembl.org", biomart="ENSEMBL_MART_ENSEMBL", dataset="mmusculus_gene_ensembl")
getBM(attributes=c("ensembl_gene_id", "chromosome_name", "start_position", "end_position", "strand", "description", "external_gene_name"), filters ="ensembl_gene_id", values = "ENSMUSG00000071528", mart=my_mart2)

Anything I can do about it?

Hi Sarah,
An alternate way of annotating your Ensembl gene would be to use the Bioconductor package AnnotationHub.
It contains gtf files from Ensembl release 69 to 81 for all organisms released by Ensembl.
The data is presented as GRanges which can easily be manipulated to get information about the gene, exons, CDS etc..
Load the package

Or a similar approach, based on Sonali's answer above:
Generate an EnsDb (Ensembl DB annotation object/database from the ensembldb package) for the specified Ensembl version:
First using Sonali's code to get the GRanges object:
> library(ensembldb)
> library(AnnotationHub)
> ah = AnnotationHub()
gtf <- query(ah, c("gtf","mus musculus", "80", "ensembl"))
gtfFile <- gtf[[1]]
snapshotDate(): 2015-08-26
Then build an EnsDb database file from that

Which you can R CMD build and R CMD INSTALL and thus have it always available locally, or just use it right away:

Hi Sarah,
Sorry that you're having problems with Ensembl data. As it happens, it
seems that a redirection was not fully in place. The problem should now
have been fixed already.
Again, sorry for the inconvenience.
