To define the "Matryoshka" based model sub-regions features, some parameters of the script should be adjusted to match your analysis needs.

• INPUT_TAG: Set the source object(s) TAG. The outer shape of this/these object(s) is used tp create the concentric, inner, sub-volume.
• NUM_INNER_OBJECTS: Set the total number of concentric sub-volumes. The parameter includes the outer source shape.
• WITH_HOLES: If True, the inner sub-volume is subtracted from the outer contiguous, shape.
• Verbose_txt_path: If not empty, the warning and error messages are saved as a TXT file. Important note: Digit a valid folder name.
  

Use the \\ or the / separators for the path string.
It is suggested to set the Verbose folder. The messages generated during the script run can help the developer team in case of issues.

The WITH_HOLES parameter changes how the inner sub-volume of each Doll is computed. It can be hollow or filled.

WITH_HOLES = True

WITH_HOLES = False
