[BioC] Unable to Generate QC Report for mogene10stv1

Hi Rick,
After all that, the reason is really simple. You are trying to use
affyQCReport on a PM-only chip, which isn't going to work out so well. I
don't have any mogene data around to play with (and don't have the time
to go searching), so I will have to make some educated guesses.
Internally in signalDist() you are calling boxplot() and hist() on your
AffyBatch. And the default for both functions is to use both PM and MM
probes. I'm betting that
any(duplicated(unlist(indexProbes(mydata, "both"))))
returns TRUE, indicating that indexProbes doesn't work correctly on a
PM-only chip, which is fair enough, as it was never designed to do so.
And plot(qc(mydata)) will never work, as it relies on computing a
Wilcoxon signed-rank between the PM and MM probes, and since you don't
have MM probes, well you get the picture...
Best,
Jim
