The Analyze Arbor widget shows different statistics on whole neurons and different parts of them. Its working set of skeletons is shown in the table at the top, which skeletons can be added to or removed from through the source selector and buttons like Append in the widget toolbar, like it is the case with many widgets.
This table is divided into information on four different views on a neuron, which are determined by CATMAID automatically by assuming the root node of a skeleton is at its soma and the end of visible microtubules are marked using the microtubules end tag. The neuron's axonic and dendritic parts are determined using flow centrality (FC). If no axon terminals can be determined through synapse clustering and FC, dendrites will be considered everything not part of the backbone (see below):
For each of those a set of statistics is listed:
The second part of the widget visualizes various histograms and statistics for each part.
