Filter out genes with detection p -value above:
In this option and the one below, you can specify values to use for filtering out genes from the output data set. If the percentage (specified in the following option) of samples have a detection p-value above the value specified in this option, the row corresponding to that gene is removed from the output data set (but not the annotation data set if a separate one is created).
Note : If you did not export the Detection Pval subcolumns from BeadStudio, no filtering is performed.
