[BioC] GenomeGraphs error

[Wolfgang Huber]

Dear Arnaud

thank you for reporting this! There were two issues:

1. GenomeGraphs tries to use the BioMart webservices at Ensembl to query 
for a property called "biotype" (a.k.a. "structure_biotype"?), which 
perhaps existed in the past but doesn't seem to be there any more. 
Steffen Durinck, the author of the GenomeGraphs package, or Rhoda might 
be able to know better what's going on here.

2. The getBM function produced a slightly obscure error message, which 
made it difficult to diagnose the error. I have fixed that in the devel 
version of the biomaRt package.

  Thank you and best wishes
	Wolfgang
