Hi Wolfgang,

Just tried both of these and I get the same error:

> mart=useMart("ensembl")
Error in curlPerform(curl = curl, .opts = opts) :
        couldn't connect to host
> mart=useMart(biomart="ensembl", dataset="hsapiens_gene_ensembl")
Error in curlPerform(curl = curl, .opts = opts) :
        couldn't connect to host

Also anytime I have put "useMart" in the argument at all it just comes up
with that error.

Any ideas?

Cheers,
Amy
