Generating 'mean/average' tracvis(.trk) file for just visualization purpose
Hello, Is there any existing way to generate 'mean' tract in .trk format? For example, generate 'average' .trk from l_Cst.trk of 30 participants data.
It's just for visualization purpose to minimize the distortion due to individual variance. So, 'adding and thresholding' might also works, but doing that brute-force approach was not successful.
Unfortunately there is no existing way for that in tractseg. You would have to write it yourself in python. (if you are familiar with python this should not be too difficult)
@wasserth Thanks so much. I have one more question. Is there any 'processable' average FA image? I can find some in brain.labsolvers.org, but they are all template, not averaged raw FA image...
When you install FSL there is folder somewhere which contains FA template/atlas images. As far as I know those are generated by averaging several FA images in one space. Maybe this can help you.
