WebHi Jahn, I've cc'd the list. Look, a lot of people say that you must must must have raw counts for this and strictly, this is true. My view is that as long as there are not too too many ambiguous reads, then this portioning off of reads in a non-integer fashion to features will not create such a huge violation of the edgeR modeling assumptions.
