• Select your gene list from the Filter base on spreadsheet drop-down menu; here, we selected Down_Syndrome_vs._Normal
• Select the column of your gene list that matches the column IDs you want to filter from your probe intensities spreadsheet; here, we selected 2. Probeset ID
  
• Select OK to apply the filter

A black and yellow horizontal bar will appear at the bottom of the spreadsheet. This is the filter indicator showing the proportion of samples columns (genes/probesets) filtered out (black) and retained (yellow). To continue working with the filtered probe probeset intensities, we can clone the filtered spreadsheet.

• Select ()
• Name the new file; we chose Down_Syndrome_vs_Normal_Probe_Intensities

Now we have a probe intensities spreadsheet containing only the probe intensity values for our 23 genes of interest (Figure 4).

...

We can now invoke the Violin plot. Make sure to have the filtered probe intensities spreadsheet selected (in blue) in the spreadsheet tree as shown (Figure 4).
