Segmentation Template Editor

Segmentation Template Editor is a 3D Slicer extension to save and apply reusable label groups for Segment Editor.
Each label is assigned a visually distinct color using golden-ratio hue stepping, allowing for fast and consistent anatomical labeling.

---

Features

• Define label sets and save them as reusable groups
• Auto-assign visually distinct colors using golden-ratio hue stepping
• Apply saved label groups to any existing segmentation in Segment Editor
• Prevent duplicate label creation and handle confirmation safely
• Groups are persisted in labels.json and shared across projects

---

How to Use

1. Enter Labels and Save a Group

• Enter label names line-by-line (e.g., left renal artery, right renal artery, etc.)
• Input a group name (e.g., Abdomen vessels)
• Click Save label group

Labels will be saved with auto-assigned colors. Duplicate or empty lines are ignored. If a group already exists, overwrite confirmation will appear.

---

2. Apply Group to Segment Editor

• Select a saved group from the dropdown
• Click Apply selected group

A confirmation popup will appear showing the current segmentation name.
This helps avoid accidental application to the wrong segmentation.

If duplicate labels already exist in the segmentation, you’ll be asked whether to skip them.

3. View Results in Segment Editor

• Newly applied segments will appear with distinct colors
• Colors are assigned using golden-ratio hue stepping to reduce similarity

Segments are automatically linked to the master volume and displayed with their assigned colors.
