GDI values are stored as metric signals, and can be plotted in Sift. The following figures show two examples of ways to compare total GDI scores and individual Left vs Right GDI scores. Further Queries could be defined to compare different conditions or sub-groups in the data set ([[Other: | GDI values are stored as metric signals, and can be plotted in Sift.
