The algorithm for detecting up-regulated genes. The high level algorithm involves the following procedures: 1) eliminate the probe sets with signal Detection calls of "Absent" in the treatment samples; 2) select the probe sets with signal Change calls of "Increase"; 3) eliminate the probe sets with a Signal Log Ratio below a threshold defined by the user; and 4) remove the probe sets with a p-value above a threshold defined by the user.
