Hi to all,
I am trying to invoke the following R code,
ensembl = useMart("ensembl");
ensembl = useDataset("drerio_gene_ensembl", mart=ensembl);
ids <- getBM(attributes = c("ensembl_gene_id","agilent_g2519F"), filters
= "with_agilent_g2519f", values =TRUE,mart=ensembl);
but the result is always the same:
1 Query ERROR: caught BioMart::Exception::Usage: Attribute
agilent_g2519F NOT FOUND
Error en getBM(attributes = c("ensembl_gene_id", "agilent_g2519F"),
filters = c("with_agilent_g2519f"), :
Number of columns in the query result doesn't equal number of
attributes in query. This is probably an internal error, please report.
However, if I retrieve the list of available attributes I can see
"agilent_g2519F" in the list.
Can you help me? There is a mistake in my code or there is something
wrong in biomart?
Thanks in advance,
Rubén.
