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.)

Data:
 *.CEL files

R version 3.1.1 (2014-07-10)

Platform: x86_64-apple-darwin13.1.0 (64-bit) 



After setting work directory to aromaaffy_test/

Rcode:
library(aroma.affymetrix)



verbose <- Arguments$getVerbose(-8, timestamp=TRUE) 

cdf <- AffymetrixCdfFile$byChipType("HuEx-1_0-st-v2")

cs <- AffymetrixCelSet$byName("GBM", cdf=cdf) 

setCdf(cs, cdf) 

bc <- RmaBackgroundCorrection(cs)
 


csBC <- process(bc,verbose=verbose) 

qn <- QuantileNormalization(csBC, typesToUpdate="pm") 

csN <- process(qn, verbose=verbose)
 


getCdf(csN) 

plmTr <- ExonRmaPlm(csN, mergeGroups=TRUE)
 

plmEx <- ExonRmaPlm(csN, mergeGroups=FALSE) 


 

fit(plmTr, verbose=verbose)
 
cesTr <- getChipEffectSet(plmTr) 

trFit <- extractDataFrame(cesTr, units=NULL, addNames=TRUE) 

trFit.mat <- extractMatrix(cesTr, units=NULL, addNames=TRUE) 


 

fit(plmEx, verbose=verbose) 

cesEx <- getChipEffectSet(plmEx) 

exFit <- extractDataFrame(cesEx, units=NULL, addNames=TRUE) 

exFit.mat <- extractMatrix(cesEx, units=NULL, addNames=TRUE) 


 

firma <- FirmaModel(plmTr) 

fit(firma, verbose=verbose) 

fs <- getFirmaScores(firma)


Error:

Getting terminated at:

fit(plmTr, verbose=verbose)


Error Message:
Error in readCel(getPathname(this), indices = idxs, readIntensities = FALSE, 
:

 

Argument 'indices' is out of range [1,284622]. 

In addition: Warning message: 

In (ns == 0L) & (nchar(unitNames) == 0L) : 

longer object length is not a multiple of shorter object length



I did the same error earlier, when i used extended CDF's 
HuEx-1_0-st-v2,extendedR3,A20071112,EP.cdf.gz
Extended + Core probesets: 147,476 units/transcript clusters, 804,085 
groups/probesets, and 3,095,094 probes)


I have following two queries.

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?  


Best regards

Manoj
