[BioC] oligo: error in crlmm function

[Javier Pérez Florido]

Dear list,
I'm trying to obtain genotype calls from genome wide SNP arrays  
(affymetrix 6.0) using oligo package, but the following error comes up:

library(oligo)
fullFilenames<-list.celfiles(full.names=TRUE)
fullFilenames
[1] "./E10897_(GenomeWideSNP_6)_2.CEL" "./E10905_(GenomeWideSNP_6).CEL"
[3] "./E10906_(GenomeWideSNP_6).CEL"   "./E10915_(GenomeWideSNP_6).CEL"
[5] "./E10916_(GenomeWideSNP_6).CEL"
outputDir<-file.path(getwd(),"crlmmResults")

crlmm(fullFilenames,outputDir)
Loading required package: pd.genomewidesnp.6
Loading required package: RSQLite
Loading required package: DBI
Loading results from previous normalization/summarization step.
Error in readChar(con, 5L, useBytes = TRUE) :
   cannot open connection
Además: Mensajes de aviso perdidos
In readChar(con, 5L, useBytes = TRUE) :
   cannot open compressed file 
'/media/data/ArraysSNPs/PTC/prueba/crlmmResults/NormalizationSummarizationOutput.rda', 
probable reason 'No such file or directory'

The output directory exists and has correct permissions.
Any tips?
Thanks in advance,
Javier
