* @brief read vtkTree from Newick formatted file
|
|
*
|
|
* vtkNewickTreeReader is a source object that reads Newick tree format
|
|
* files.
|
|
* The output of this reader is a single vtkTree data object.
|
|
* The superclass of this class, vtkDataReader, provides many methods for
|
|
* controlling the reading of the data file, see vtkDataReader for more
|
|
* information.
|
|
* @par Thanks:
|
|
* This class is adapted from code originally written by Yu-Wei Wu.
