This page provides collective information about the selected dataset, gene list submitted (and the actual number of probes found on this platform) as well as sample groupings associated with this dataset. In this example, select ``tumorSize-quartiles'' as sample grouping in step 2. We do no want to filter any samples hence we can skip step 1. Also, select ``computeLR'' and press ``Analyze'' button. Figure depicts the snapshot of this step.
