Hi all,

I am facing a scan error when using getBM with a mart that is not ensembl. The code below worked fine like a year or two ago, but I recently figured that it stopped doing that (I was upgrading my OS and R in between). Unfortunately, I don't know how to handle the error, the Mart object looks fine. Help is much appreciated!

Thanks a ton, Rebecca

Error in scan(file = file, what = what, sep = sep, quote = quote, dec = dec,  :

I don't have these problems when I pick for example the Drosophila dataset from Ensembl.

It looks like VectorBase automatically redirects you to the https version of their site. biomaRt should be able to cope with this, but clearly it doesn't, so we'll have to be explicit. Try this for setting the mart host:

VB = useMart(host = "", biomart = mart, port = 443)

I'll try to track down why biomaRt doesn't work this out for itself.
