I would like to ask you a question regarding the behaviour of CopywriteR in the regions of very low coverage. In some cases, the results that I obtained from CopywriteR shows a number -1073741823.5 (like below). I would like to confirm if this is in fact the result of very low read coverage of that region (which is the case here), hence it is a representation of -infinity as we're trying to calculate logarithm from around 0 or this number -1073741823.5 means something else.
