Table 1.
Partial list of LM metrics (the unit for all dimensional values is μm). All metrics return real values unless otherwise noted. Metrics in the left column return values at each tracing point except the gray shaded ones, which are defined at the whole neuron level. Metrics in the right column return one value for every branch, except the gray shaded ones, which are defined at bifurcation points only.
