Two spreadsheets are created, similar to the spreadsheets in the de novo motif discovery, the motif_summary (MotifSearch) spreadsheet (Figure 67) and the motif_instances (MotifSearch.instance) spreadsheet. 

...

As you can see, REST, which is another name for NRSF, is near the top of the list as one of the most significantly over-represented motifs (Figure 67). This motif agrees with the motif found in the de novo motif detection step. Interestingly, other motifs appear a significant number of times in the ChIP-Seq peaks and may represent possible co-factors or regulators.

• Select the motif_instances spreadsheet in the spreadsheet tree 
• Right-click the 5. Motif Name column 
• Select Find / Replace / Select... from the pop-up menu (Figure 78)
  
  

• Set Find What: to REST
• Select By Columns for Search: 
• Select Only in column with 5. Motif Name selected form the drop-down menu
• Select Select All (Figure 89)
  
  

...

• Right-click on the first highlighted row visible; in this example, we see row 13196 
• Select Filter Include from the pop-up menu (Figure 910)
  
  

The spreadsheet will now include 2098 rows and a black and yellow bar will appear on the right-hand side of the spreadsheet (Figure 1011). The black and yellow bar is a filter indicator showing the fraction of the spreadsheet currently visible as yellow and the filtered fraction as black.
