  • Select or create an ROI covering the vessel region to analyze.

See Using the GUI for loading files and ROIs.

Run diameter analysis in the GUI

  1. Select the file, channel, and ROI in the file list.
  2. Open the left navigation toolbar and click Diameter (straighten icon).
  3. Review Detection parameters in the Diameter panel.

Results and reproducibility

Review diameter results in the Diameter panel and the Analysis plot. Save from the load/save controls to write JSON and CSV files next to the source image. See Saved file formats for output file details.

Saved files

For a source file named my_file.tif:

my_file.tif.json
my_file.tif.diameter.csv

The JSON file stores detection parameters and summary values (for example mean diameter and QC scores). The CSV stores tabular diameter results.
