[BioC] Errors in importing cel files into oneChannelGUI

[Ester Feldmesser]

Hi everybody,

I have recently installed oneChannelGUI and all the Affymetrix Power 
Tools (apt-1.6.0) in a PC. The installation went OK. I am trying to 
analyze Affymetrix Rat exon chips, I wanted to import CEL files and 
apply iter-plier for gene level and rma-sketch for exon level intensity 
summaries. After defining all the paths (ATP, library, working directory 
and targets file) and the summarization method, I've got  the following 
error reports in the R console and the CEL files were not imported.

Gene level probe sets summary started

Gene level probe sets summary ended
Error in as.matrix(my.exons) :
  no function to return from, jumping to top level
In addition: Warning messages:
1: In system(gene.iterplier, wait = T) : C:/Program not found
2: In dir(tempOut) :
  list.files: 'D:/Researchers/Weizmann Institute/Biological 
chemistry/.../out72ae2cd6' is not a readable directory
3: In file(file, "r") :
  cannot open file 'D:/Researchers/Weizmann Institute/Biological 
chemistry/.../out72ae2cd6/', reason 'No such file or directory'

Do anybody has any idea what went wrong and how to repair it?
Thanks,
Esti
