Dear All.

I try to make some comparison using RIPSeek I have this error on Centos 7.0

> bamFiles <- list.files(extdata.dir, "accepted_hits.bam$", recursive=TRUE, full.names=TRUE)
> ctlIgM <- combineAlignGals(grep(pattern="IgM", bamFiles, value=TRUE, invert=FALSE),reverseComplement=TRUE, genomeBuild="hg19")
Processing /home/mauro/Desktop/Analisi_ripseek/mitico/RIP1-IgM_R1/accepted_hits.bam ... Error: cannot allocate vector of size 2.3 Gb
