Create Mapping Graph

Create Mapping Graph can create a range of different graphs from a read mapping track. To run the tool, go to:

        Toolbox | Utility Tools (Image utilities_closed_16_n_p) | Tracks (Image track_tools) | Graphs (Image graphs_closed_16_h_p) | Create Mapping Graph (Image graph_track_16_n_p)

Select a read mapping as input (figure 27.32).

Figure 27.32: Mapping graph tracks containing different types of information can be created using Create Mapping Graph.

Select the graph track types to create (figure 27.33). One graph track is created for each type selected.

Each position in a graph track contains the values of the track type selected. These are:

An example of three different outputs is shown in figure 27.34.

The option "Fix graph bounds" found under Track layout in the Side Panel is useful to manually adjust the numbers on the y-axis.

When zoomed out, the graph tracks are composed of three curves showing the maximum, mean, and minimum value observed in a given region (figure 27.37). When zoomed in to single base resolution only one curve is shown, reflecting the exact observation at each individual position (figure 27.35).
