I'm dealing with nifti file currently, and I cannot find way to extract segmentation info (or data) from it.

  1. I have a {filename}.nii.gz file and read this file with NIFTI-Reader-JS package, render it into html canvas. enter image description here

  2. As you can see, the brain image have separated areas that can be recorgnized with its color.

  3. Q1. But how can i get each segmentation info from NIFTI-Reader-JS package or anything else? I checked all header info from this file but cannot find any hint.

  4. When I open this file whit 3D Slicer in windows, I can choose segmentation option and it renders more specifically with various colors. And that's what I want to do with javascript. enter image description here

My english is not good enough, so if anyone have a question or need more specific instructions please tell me.

Thanks for all your helps.
