[Bioc-devel] Error on Windows when selecting a single chromosome from a BSgenome

[Bernat Gel]

Hi all,

We are trying to get our first package (regioneR) included into 
Bioconductor. A couple of months ago it passed all the automatic checks 
but now, without code changes from our part fails on windows.

I've been digging and it seems the problem arises when selecting a 
single chromosome from a BSgenome object.

library("BSgenome.Hsapiens.UCSC.hg19.masked")
BSgenome.Hsapiens.UCSC.hg19.masked[["chr1"]]

This works in linux and mac but in windows it kills R without any error 
message. Any idea of what's going on?

Our final aim when doing that is to have a data.frame with the genomic 
coordinates of the masked regions, so if there's an alternative approach 
we could use it as a workaround.

Thanks a lot!

Bernat
