Part D: Map a filtered set of features

In this example, you will map only CDS features which have a note containing the letters RB.

1. Right-click on the name of the source (upper) sequence and select Features > Map Features to Bottom Sequence. The Map Features wizard launches.

2. In the Features screen, select the features you want to include or exclude in the mapping:
   
   
   1. From the upper drop-down menu, choose Features matching.
      
      
   2. From the menu just below that, select CDS.
      
      
   3. To restrict mapping to features that have a note containing the letters “RB”, check the Filter box and select /note from the drop-down menu to its right. In the text box, type in *RB*. The asterisk wildcards are used so that any text string containing RB will be included.
      
      
   4. Click Next.

3. In the Options screen, the Mapping sliders and corresponding text boxes are used to specify the feature coverage and sequence identity thresholds that are required to map a feature. Change both items to 90% to make mapping extra stringent. Leave other items at their default settings and click Next.

4. In the Output screen, type in the Project name “CDS-RB features” and save the project in the same location as the other output file.

5. Click OK to initiate feature mapping.
