Hi Ina, I've just looked at the code and the call to imageplot() in expressionQCPipeline() does indeed have useLocs = TRUE, so it's probably the issue. I've added the patch we've used in the devel version to release 2.0.6. If you update to that, both imageplot() and expressionQCPipeline() should both work with the locs file. If it's still causing errors let us know and we'll add an argument to expressionQCPipeline() allowing the user to toggle the useLocs argument. I hope that helps, On Mon, Mar 7, 2011 at 2:55 AM, Ina Hoeschele <inah@vbi.vt.edu> wrote: > thank you, Mike, doing the image plots with useLocs = FALSE works and is > good enough ...
