RNA Seq // QuasR : Error while extracting unmapped reads

Question

[guillaume.dachy]

Hi everyone,

I'm trying to use the QuasR package for paired-end RNA Seq for his precious function allowing to align an auxiliary genome, but I get some trouble which are maybe very naive ... but hard to resolve for me !

Does this following error message give an idea to someone ?

> file.copy(system.file(package="QuasR", "extdata"), ".", recursive=TRUE)
[1] TRUE
> sampleFile <- "extdata/samples_rna_paired_copie.txt"
> genomeFile <- "BSgenome.Mmusculus.UCSC.mm10"
> auxFile <- system.file(package="QuasR", "extdata", "auxiliaries_copie.txt")
> proj <- qAlign(sampleFile, genome=genomeFile, auxiliaryFile=auxFile, splicedAlignment=TRUE)
alignment files missing - need to:
    create 2 auxiliary alignment(s)
will start in ..9s..8s..7s..6s..5s..4s..3s..2s..1s
Testing the compute nodes...OK
Loading QuasR on the compute nodes...OK

I didn't find anything similar on the forum...

Thank you very much for your help !!
