Hello,
I am using R-dev, and would like to run QuasR to align a RNA-seq
experiment.
Unfortunately, I can't get past the indexing step because somehow
BSgenome cannot be accessed by QuasR.
I think this is due because it can be accessed by using "Rnorvegicus"
rather than by (the expected) "BSgenome.Rnorvegicus.UCSC.rn5".
Is this to be changed in QuasR, or the BSgenome?
Thanks,
Guido

alignment files missing - need to:
create alignment index for the genome
create 18 genomic alignment(s)
will start in ..9s..8s..7s..6s..5s..4s..3s..2s..1s
Error in get(genome) : object 'BSgenome.Rnorvegicus.UCSC.rn5' not

The specified genome is not a fasta file or an installed BSgenome.
Connecting to Bioconductor and searching for a matching genome
(internet connection required)...OK
Bioconductor version 2.14 (BiocInstaller 1.13.3), ?biocLite for help
Error: Rnorvegicus is not available in Bioconductor. Type
