I am interested in typical developmental effects of fixel metrics:
Some mean metric of different WM bundles ~ age + sex
For visualization purposes, I am trying to color the different WM bundle (tracts) based on the age t-value from my statistical model in mrview. I know it is possible to do so by loading a .txt file in the option of mrview in tractography. Does anyone have an example of such .tsf or .txt file? I have created a .txt file with the t-value, but it’s wrong because I always get:
The scalar text file does not contain the same number of elements as the selected tractogram
How should one create this .txt file?
Thank you for all the help,
