Running the duplicate reads removal

The tool is found in the Toolbox:

        Toolbox | NGS Core Tools (Image ngs_folder_open_16_n_p) | Remove Duplicate Mapped Reads (Image remove_duplicates)

This opens a dialog where you can select mapping results in read tracks (Image read_track_16_n_p) format. Clicking Next allows you to set the threshold parameters as displayed in figure 25.43.

The parameter is explained in detail in Algorithm details and parameters.

Clicking Next will reveal the output options. The main output is a list of the reads that remain after the duplicates have been removed. In addition, you can get the following output:

List of duplicate sequences
These are the sequences that have been removed.
This is a brief summary report with the number of reads that have been removed (see an example in figure 25.44).
