I'm trying to get yeast and human protein sequences, and the human one works, but yeast doesn't - anyone know what's going on? Here is my code:
>>> server = pybiomart.Server(host="http://www.ensembl.org")
>>> mart = server["ENSEMBL_MART_ENSEMBL"]
>>> hsapiens_dataset = mart["hsapiens_gene_ensembl"]
>>> scerevisiae_dataset = mart["scerevisiae_gene_ensembl"]
>>> hsapiens_df = hsapiens_dataset.query(attributes = ["ensembl_peptide_id", "peptide"])
>>> hsapiens_df
Peptide Protein stable ID

Traceback (most recent call last):

raise BiomartException(response.text)
pybiomart.base.BiomartException: Query ERROR: caught BioMart::Exception::Query: returning undef ... missing attributes for your exportable?
Update: there appears to be an error on BioMart's end, because I get the same error if I try to query the peptide sequence through the BioMart website. Is it happening for others?
