Hi Johanna, I hope you are well :) Do you know of any alternative to using Threshold in macro, so that it automatically matches the result of each image? Because each image generates different values, and there is no way I can provide a fixed value that works for the entire set of images (there are many)

Hi @claireseelingbranscomb2781. Go to 3D OC Options first. Check the Maps' parameters and make sure Show numbers and White numbers are checked. To merge images, you have to convert one of them to match the other. For example, if the 3D Objects Map is 16-bit, check that your original image has the same bit-depth. othrwise, go to Image-Type and choose 16-bit.

@@sriti_hikari Since each image in a z-stack is an optical section of your sample, fiber orientation shows the angle per slice. If you do a maximum projection of your z stack and then run the plugin, the orientation is based on the xy plane.

What about if I want to make four quadrants of a circle in ROI and segment them to analyze 4 different area from the intersection of a circle and 2 lines (vert and horz)? Can I do that? I haven't seen anyone do this in ROI yet. Thanks
