Axon-dendrite split points calculated for all hemibrain neurons

Source: R/hemibrain_data.R

Axon-dendrite split points calculated for the whole hemibrain dataset, hemibrain:v1.0.1, using a variety of parameters. The file used to generate this can be found in this package, as data-raw/hemibrain_split_all_neurons.R. The arguments given to flow_centrality are in the name of the data frame. Note that, because the proportion of recovered synapses is unevenly distributed across brain regions, after compartment detection, sometimes the dendrite was chosen as the neurite closest to a neuron's primary branch point (data frames with 'distance' in their name), see reference.
