I am working on measuring collagen fiber thickness using both DiameterJ Segment and DiameterJ 1-018 plugins. I have successfully segmented the images but am unsure if I have entered in the correct scale bar for the DiameterJ 1-018 analysis. I believe my scale for the original image was 68 pixels/cm, which would convert to 680,000 pixels/micron. Does this value sound legitimate? It was taking my computer a long time to analyze the picture with this input so I had to stop the analysis. Thank you.
