HI, I am trying to obtain transcript level expression using Aroma.affymetrix /FIRMA. I did following steps,
*Creating directories*: work directory: aromaaffy_test CDF dir: aromaaffy_test/annotationData/chipTypes/HuEx-1_0-st-v2/ Data dir: aromaaffy_test/rawData/GBM/HuEx-1_0-st-v2/ *CFD: * HuEx-1_0-st-v2.cdf (name changed; downloaded from HuEx-1_0-st-v2,coreR2,A20070914,EP.CDF <http://bcgc.lbl.gov/cdfFiles/HuEx-1_0-st-v2,A20070914,EP/HuEx-1_0-st-v2,coreR2,A20070914,EP.cdf> [38 MB] Core probesets: 18,708 units/transcript clusters, 284,258 groups/probesets, and 1,082,385 probes.)

Could you let me know where I am doing wrong? Also, is it possible to get the expression values of the isoforms, corresponding to ENSEMBL ID,( i.e. ENSTxxxxxxxxx format) using this package?
