Create Macro:

Plugins -> Macros -> Record


  1. Find image scale.

Draw line over embedded scale bar. Go to Analyze -> Set Scale, enter known length of scale bar to get pixels/µm.


  1. Set scale

Analyze -> Set Scale (6.9 pixels/µm, for our 63x, 1024 x 1024 confocal images) *depends on microscope/image acquisition; calibrate to image stack as described above


  1. Filter to remove the noise.
    Process -> Filters -> Gaussian Blur (2.00)


  1. Subtract the background.
    Process -> Subtract Background (50)


  1. Threshold your image.
    Image -> Adjust -> Threshold (used 4), then check “dark background” - background should be black and nuclei white


  1. Fill in any holes in the nuclei.
    Process -> Binary -> Fill Holes


  1. Separate “Touching” nuclei.
    Process -> Binary -> Watershed


  1. Find Edges
    Process -> Find Edges


  1. Count nuclei

Analyze -> Analyze Particles (Size (pixel^2): 1000-infinity; Circularity: 0-1; check Pixel Units, Add to Manager, Exclude Edges)


  1. Close DAPI image.


Save Macro:

Save As “2D_FindNuclei.txt”


  1. Open corresponding YAP image.


Create 2nd Macro:

Plugins -> Macros -> Record


  1. Set Measurements

Analyze -> Set Measurements, select Area, Center of Mass, Bounding Rectangle, Shape Descriptors, Integrated Density (Mean Gray Value times Area), Skewness, Mean Gray Value (sum of all gray values of all pixels divided by number of pixels), Perimeter


  1. Set scale

Analyze -> Set Scale (6.9 pixels/µm)


  1. Overlay outlines of nuclei into YAP image.

Open ROI manager (if not already open)

    Analyze -> Tools -> ROI Manager

In ROI Manager, select Show All

In ROI Manager, select Measure


  1. Save results

File -> Save As, save to Desktop as “Results”


Save Macro:

Save As “2D_AnalyzeIntesityinNuclei.txt”


To run:


  1. Open DAPI image.


  1. Run Macro

Plugins -> Macros -> Run “IF_FindNuclei.txt”


  1. Open corresponding YAP image.


  1. Run Macro

Plugins -> Macros -> Run “IF_AnalyzeIntesityinNuclei.txt”


  1. Rename “Results” on Desktop.

Create Macro:

Plugins -> Macros -> Record


  1. Find image scale.

Draw line over embedded scale bar. Go to Analyze -> Set Scale, enter known length of scale bar to get pixels/µm.


  1. Set scale

Analyze -> Set Scale (3.45 pixels/µm, for our 63x, 512 x 512 confocal images). *depends on microscope/image acquisition; calibrate to image stack as described above


  1. Filter to remove the noise.
    Process -> Filters -> Gaussian Blur (2.00)


  1. Subtract the background.
    Process -> Subtract Background (50)


  1. Threshold your image. *image acquisition-dependent; calibrate to image stack
    Image -> Adjust -> Threshold (used 17), then check “dark background” - background should be black and nuclei white


  1. Fill in any holes in the nuclei.
    Process -> Binary -> Fill Holes


  1. Separate “Touching” nuclei.
    Process -> Binary -> Watershed


  1. Find Edges
    Process -> Find Edges


  1. Count nuclei
