Hi,

I am trying to use gcrma for the mouse GNF/Novartis data.
This dataset use a custom affy chip gnGNF1Musa. I got the CDF file and 
probe file from GEO.


 > library("gngnf1musacdf")
 > library("gngnf1musaprobe")
 > eset.gcrma<-gcrma(Data)
Adjusting for optical effect.......[more dots].....Done.
Computing affinitiesError: length(prlen) == 1 is not TRUE


I create the CDF package like this:
 > library(makecdfenv)
 > make.cdf.package("gnGNF1Musa.cdf", species = "Mus_musculus")
then $> R CMD INSTALL gngnf1musacdf



When I create the probe package, I have a warning. I don't know if it's 
linked to the gcrma error have.

 >  makeProbePackage("gnGNF1Musa", datafile = filename, outdir = outdir, 
maintainer = me, species = species, version = "0.0.1",force = TRUE)

Do you think that the error I get from gcrma is linked to the cdf/probe 
package I have made. I also noticed that the probe file I have, has one 
extra column called "Serial Order". Do you think it might explain the 
gcrma error ?

Probe Set Name  Serial Order    Probe X Probe Y Probe Interrogation 
Position    Probe Sequence  Target Strandedness
