UNVEIL

UNVEIL is a Python-based visualization tool for interactive exploration of diffusion MRI tractography, anatomical volumes, cortical surfaces, and ROI segmentations. It combines a 3D PyVista viewer with an orthogonal slice viewer.

Install

The GUI is launched with the following python command in a python console:

import unveil.__main__

or with

python -c "import unveil.__main__"

from a terminal with a python environment activated.
