Only tbe standard three-point soma type and a multi-cylinder description are supported.

Furthermore, the root node of the tree must have index == 1, swc_type == 1 and occur first in the SWC file.

file_n (string) – Name of the file containing the SWC description

Returns:

soma_type – Integer indicating one of the su[pported SWC soma formats. 0: One point soma 1: Default three-point soma, 2: multiple cylinder description
