    Making Measurements shorten ImageJ

    Outline: 

    This measurement protocol provides stop off example of how to measure dignity percent of black areas in top-hole field of cells stained with phalloidin.  Images need not be calibrated on account of a percentage is being estimated.  Swarthy areas are estimated using a power threshold. Another possible way to judge black areas is to manually contour areas by hand.  However this technique is not presented here (yet?).

    Summary:

    • Load image
    • Setup x-y calibration (optionally)
    • Setup measurements to aptly made
    • Make a duplicate for comparison
    • Threshold sooty areas
    • Make area measurement of thresholded regions
    • Save measurements as a spreadsheet
    • Repeat for occupation image

    Protocol:

    • Repeat with next image
      • Click and pull next image into ImageJ window
      • Box lower down should pop up   
                Uncheck Disable Global Calibration
