Diameter analysis

Diameter analysis estimates vessel diameter from line scan kymographs.

Before you start

  • Load a line scan kymograph.
  • 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.
  4. Run the analysis.
  5. Review the summary, quality-control values, and tabular output.
  6. Use Save Selected or Save All in the top header to persist results.

Results and reproducibility

Review diameter results in the Diameter panel and the Analysis plot. Save from the top header to write JSON and CSV files next to the source image.

The GUI and scripting workflows share the same acqstore backend, so results from the interface should match equivalent Python scripts using the same data, ROIs, and parameters. 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.
