Cell Position Output

When NCS required the distance between cells (for the computation of synaptic delays), the cells needed to be assigned specific coordinates (x,y,z). Cells are assigned their positions based on information from the input file.

Column

The Column has an x, y coordinate pair for the center of the base
It also has width and height parameters. Width establishes the maximum distance a cell can be from the center of the column. Height will be used in conjunction with Layer parameters.

Layer

The Layer puts limits on the height parameter of the Column. It applies Upper and Lower percentages to select a subset of the Column's height and limit a cell's z coordinate to that subset.
