Stereology

Back to MIB | User interface | Menu | Tools

Counts intersections between model materials and grid lines, with spacing definable in pixels or image units. Results can be exported to MATLAB or Excel.

Demonstration

Details and parameters

Generate the grid with the Generate button in the Grid options panel.
Start analysis with the Do stereology button.
The Include annotations checkbox also calculates occurrences of annotation labels from the Segmentation Panel → Annotations.

Warning

When grid thickness is 1 pixel (grid extra thickness = 0), the grid may not display properly below 100% magnification. Increase extra grid thickness to view at lower magnifications.

Info

Style of the mask layer can be switched from contours to solid lines from
Menu->File->Preferences->Colors and styles->Masks->show as contours
