Dear Bioconductor users,

I used arrayQualityMetrics to generate quality report. But, in its summary
report, how does it determine array which has potential problem or as being
an outlier? I mean, is there some kind of cutoff  for MA, Boxplot and
heatmap? If it is yes, where can I find them?

What is saturation effect? What is  background intensity distributions. Dr.
Hunber explained it before on how to interpret the *Standard deviation
versus rank of the mean*, but I still do not understand its biological
meaning.

Thanks in advance.
