Hi Martin, while you are at it, Do you think you could also expose the samtools cat command at the R level? (from the samtools help: http://samtools.sourceforge.net/samtools.shtml) samtools cat [-h header.sam] [-o out.bam] <in1.bam> <in2.bam> [ ... ] While functionally this can already be done using mergeBam(), samtools cat is way faster. This is e.g. useful when you already have sorted bam files per chromosome and want to combine them. thanks Jens On Fri, Aug 29, 2014 at 1:36 PM, Jens Reeder <jens.reeder at="" gmail.com=""> wrote: > That's great to hear. > I'll keep an eye open for the new Rhtslib. > > Hopefully the windows issues will not keep it out of the next bioc release. > > thanks > Jens > > > On Fri, Aug 29, 2014 at 1:26 PM, Martin Morgan <mtmorgan at="" fhcrc.org=""> wrote: > >> On 08/29/2014 10:36 AM, Maintainer wrote: >> >>> Hi Jens, >>> >>> Note that if you have a large number bam files, you can already sort >>> them in parallel using BiocParallel or your favorite parallel variant >>> of lapply.
