Hi,

I have run into an issue with the listMarts function. When I type in useMart, the following error comes up:

ensembl<-useMart("ensembl")
Error in listMarts(host = host, path = path, port = port, includeHosts = TRUE, :
Unexpected format to the list of available marts.
Please check the following URL manually, and try ?listMarts for advice.
http://www.ensembl.org:80/biomart/martservice?type=registry&requestid=biomaRt

The sessionInfo is as follows:

I checked the URL and ?listMarts which said to report the issue. When I check the above URL, it does start with <MartRegistry>. I was able to run this fine on Friday evening (Dec 8, 2017) and am wondering why it no longer works. I am very new to Bioconductor and any help would be appreciated.

Thanks!
Jen

I can confirm the present server issues.

Below, for example, the first two requests below succeed and the later two fail:

> useMart(biomart='ensembl', dataset='hsapiens_gene_ensembl', host='www.ensembl.org')
Object of class 'Mart':

The same issue when using archive.ensembl.org. Has been happening since this morning or so.

Usually when this happens, switching to one of the archive servers or waiting a day or so resolves the issue. It would be nice if there was a way to print the server response associated with the failed request to see exactly what is going on.

Best,

Keith

Sometimes web resources go on the fritz momentarily. When I try to use biomaRt, it works fine:

> ensembl <- useMart("ensembl")
> listMarts(ensembl)
               biomart               version
1 ENSEMBL_MART_ENSEMBL      Ensembl Genes 91
2   ENSEMBL_MART_MOUSE      Mouse strains 91
3     ENSEMBL_MART_SNP  Ensembl Variation 91
4 ENSEMBL_MART_FUNCGEN Ensembl Regulation 91

So maybe it's just a matter of trying again.

I tried again and the same error is still coming up :(
