How to Load Existing ROI

This instruction shows how to import previously exported ROIs (see how to export a ROI in Export ROI Data) or externally defined ROIs into CartoScope.

This is useful for bringing in ROIs defined in other software (e.g., ImageJ, QPath) or from previous CartoScope sessions.

1. Prepare your ROI file

Please have your ROI file ready, which should be in GeoJSON (.json, .geojson) format.

2. Import your ROI file

1. Open ROI Drawer: Click the ROI button in the Top Bar to open the ROI Drawer.
2. Click Upload: In the ROI Drawer toolbar, click Upload.
3. Select File: A file dialog will appear. Select the GeoJSON file from your computer that contains your ROIs.

4. Review

The imported ROIs will immediately appear on the map and be listed in the ROI List within the drawer.

Tips

It is recommended to check whether your ROI is Fully Loaded or Partially Loaded in the ROI List.
