[BioC] Using \'spliceIndex\' function from \'annmap\' package: How do I know what \'ids\' should be?

[Heather [guest]]

I have cel files from Affymetrix Human Exon 1.0 arrays: 3 treated and 3 control. The files are being read together, using 'aroma.affymetrix', 'oligo', and 'pd.huex.1.0.st.v2' packages:

read.celfiles(list.celfiles("/my/directory",fullnames=TRUE)

I then used 'rma' (at the probe set level) on the raw cel files. I am now trying to use the 'spliceIndex' from 'annmap' package. I have so far:

spliceIndex(rma.output,gps=list(1:3,4:6))

But I am not sure what to put for 'ids'. The help package says ids is "Character vector of Ensembl gene names" but I am not exactly sure what that is, or where I get/make that vector. So, I am not able to run the 'spliceIndex' function.

Any help is greatly appreciated.
