Hello,
I get the following biomaRt error when trying to use the limma2biomaRt
function in conjunction with a limma fit2 object created from a MBNI
custom CDF. I thought I was faithfully following the "Annotating data
with affycoretools and biomaRt" vignette.
THE ERROR
> limma2biomaRt(eset.mbni, fit2.mbni, design.mbni, cont.matrix.mbni,
species = "hsapiens",
+ pfilt = 0.05, interactive = FALSE)
connected to: ensembl
Reading database configuration of: hsapiens_gene_ensembl
Checking main tables ... ok
Checking attributes and filters ... ok
Error: ' entrezgene 'is not an available annotation source for this
biomaRt or this species.
Available choices are listed below:
name
description
1 affy_hc_g110 Affy hc g 110
ID(s)
2 affy_hg_focus Affy hg focus
ID(s)
3 affy_hg_u133_plus_2 Affy hg u133 plus 2
ID(s)
...cutoff for brevity.
I'm fairly sure the gene IDs in fit2.mbni are indeed entrezgene IDs:
