 Third, it is not clear to me from the manuscript how confident the authors are in estimating overlap in LP and Pbg RGC pathways -- in Figure 0 for example, clusters 0,0 and 00 are inferred to be part of the Pbg pathway but clusters 0,0 and 00 are inferred to innervate both circuits, but these all appear to have similar biases or have so few neurons that the confidence intervals on the% to each pathway must be very large. The manuscript needs much greater clarity about how these inferences are made, and the statistical support that they have.
