The results of running an integrate and fire network include the timecourse of the potential at each of the recordable cells, the connectivity of the network, and the strengths of all the synapses through time. To help visualize this data it is packed in a NetView object. The NetViewEditor lets you play through the data as a movie and select cells and synapses to view in detail.

Populations marked as recordable in the network are shown by patches in the main window. Within each patch are filled circles for each cell in the population. Their colors show the potential according to the mapping defined in the ColorTable associated with the IaFCalc object. Each cell is drawn as a dot of diameter as specified with the cells arranged in ncol columns.

The buttons at the bottom can be used to play through the time evolution of the network, where the frame-rate is the number of steps shown per second as far as possible. Progress through the data is shown on the middle slider, with the current time in blue. The knob on this slider may also be moved with the mouse to select time slices.

Clicking on a cell exports its potential history to the graph window, and if the incoming or outgoing fields are selected links to pre- or post-synaptic cells are shown respectively. Active cells are shown outlined in white. Clicking again cancels the display.
