What is SWC format?
A. A file in SWC format contains information representing a digitally reconstructed neuron. SWC is non-proprietary and stores the minimum amount of parameters required to represent a vector-based three-dimensional reconstruction. Files may begin with headers above the data values, each beginning with #. Parameters are organized into 7 columns, where each row within the column represents one trace point. From left to right these columns are: unique identity value for trace point, structure type, x coordinate, y coordinate, z coordinate, radius, identity value for parent (i.e. trace point that comes before and connects to the current trace point).
