I have two granges (gr1 and gr2) in which all ranges of gr2 overlaps with ranges of gr1. How can i find granges of gr1 that are not overlaping with gr2? i.e. black color output given on the link http://bedops.readthedocs.org/en/latest/_images/reference_setops_bedops_difference_ab@2x.png

I believe "setdiff" should do what you want. Browse through this intro vignette for more info: http://www.bioconductor.org/packages/release/bioc/vignettes/GenomicRanges/inst/doc/GenomicRangesIntroduction.pdf

subsetByOverlaps(gr1, gr2, invert = TRUE)

does it.

subsetByOverlaps(gr1, gr2, invert = TRUE), is the better option if you want to keep your metadata columns!

Hi,

FWIW subsetByOverlaps(gr1, gr2) is equivalent to gr1[gr1 %over% gr2] so you would get the opposite with gr1[!(gr1 %over% gr2)]. This is not what you seem to want though: you seem to want setdiff() (thanks Steve). Just wanted to clarify the difference.
