Dear edgeR users If you are using the release version of edgeR, please ensure you have updated to the latest release version, edgeR 2.2.5. We caught a bug in exactTest() introduced in v2.2.0 that affects p-values when some rows of the count matrix are all zeros. A recent off-list question prompted me to remind everyone of this bug- fix on the list. Ideally all Bioconductor users are updating their packages very regularly, but if you haven't updated your version of edgeR lately I recommend you do it now.
