SNP Matrix

The SNP Matrix contains the pairwise number of SNP differences between all pairs of samples (see figure 9.10).

Figure 9.10: A SNP matrix.

Use the Side Panel setting Comparison gradient to get an overview of which samples are closely related. Drag the arrows to change the minimum and maximum values of the scale, or click the gradient to access the gradient configuration dialog. Use the Lower threshold field to type in a lower threshold value between 0 and the maximum value in the matrix. This results in a distinct coloring of the cells in the matrix which have a value less than the threshold.
