The user can select either individual sections, or groups and set precise parameters for length, diameter, area and length for that group or section. Any of these values can be set as a function of length or some other parameter of the corresponding section. The user can set the number of functional segments in a section, which is a strategy for spatial resolution. The higher the number of segments, the more precisely Neuron can handle a function in a section. Segments are the points where point process managers can be associated.
