I encounter strange problem when running analyze skeleton on an image - it output NaN values for “Average branch length” and “Maximum branch length” for all segments.
- I start with an image that is Probability output from Ilastik (see fibers-data_Probabilities.zip (4.8 MB) , i tried to upload the h5 file directly without zipping it, but couldn’t)
- I take only the second channel
- Skeletonize or Skeletonize 2D/3D
- Analyze skeleton
The strange thing is that if I save the image to a file at step 1 or 2 or 3 , open it again and continue the process. I get valid numbers for “Average branch length” and “Max branch length”.
I can use it as a workaround, but I would prefer not to if possible.
The image is 8-bit, 2058*1830 pixels
I use updated Fiji with ImageJ v1.52u
