Find Best References using Read Mapping

The Find Best References using Read Mapping tool maps reads to a reference sequence list to identify the best matching reference i.e., the references for which the input reads hold more evidence.

If a host genome is provided, reads that map better to the host are filtered to not have them count toward results.

To start the tool, go to:

        Toolbox | Microbial Genomics Module (Image mgm_folder_closed_flat_16_h_p) | Typing and Epidemiology (Image typing_epi_folder_closed_16_h_p) | Find Best References using Read Mapping (Image find_best_reference_w_mapped_16_n_p)

In the first dialog, select the sequences or sequence lists containing the sequencing reads, and click on Next.

In the References dialog, specify the following (figure 8.6):

In the Mapping options dialog, specify settings for the read mapping (figure 8.7). The options are identical to those of the Map Reads to Reference tool and are described here:

The Filters dialog holds the following options (figure 8.8):

In the final step, specify the output:
