TractEdit v2.0.1

TractEdit v2.0.1 (December 6, 2025)

Key Features

• ROI Filters: Implemented support for multiple independent Region of Interest (ROI) images (.nii/.nii.gz) in separate layers, including multi-selection loading. Introduced a logical filtering system with right-click options: View-only, Select, Include, and Exclude.
• Data Panel: Implemented a vertical data panel to control options, information, visibility, and features of anatomical images and tractograms, as well as the ROI-based filtering system.
• Centroid/Medoid: Implemented functionalities to calculate the centroid and/or the medoid of the edited bundle (with a safety limit for tractograms >100k streamlines and a progress bar with cancellation option).
• Sphere optimized: Optimized the sphere-based streamline selection and deletion, using bounding box and segment intersection.

Minor improvements

• Added an interactive RAS coordinate bar at the right-bottom of the main window.
• Improved affine transformations to preserve voxel resolution.
• Implemented persistent (sustained) zoom in 2D panels, and right-click "Reset Zoom" option.
• Added hover tooltips providing details on loaded data in the data panel.
• Added a "Clear All" button.
• Refactored parse_numeric_tuple_from_string and other helper functions to improve readability.
• Replaced standard print statements with a structured logging system.
• Fixed a bug causing the crosshair to disappear in the 2D sagittal plane panel when navigating the right hemisphere.
• Fixed the Anterior-Posterior labels in the 2D sagittal plane.
• Fixed greyscale color flickering issues.
• Fixed visual bugs related to ROI spatial mapping.
• Fixed flickering artifacts while moving the crosshair between slices.
• Updated the application icon.
