Since one of the t-SNE results is a matrix of two dimensions, where each dot reprents an input case, we can apply a clustering and then group the cases according to their distance in this 2-dimension map. This analysis is included in the revised manuscript (Figure 3E,F and Figure 3—figure supplement 1D,E). Visualizing high-dimensional data by projecting it into a low-dimensional space is a classic operation that anyone working with data has probably done at least once in their life.
