Map scalar maps onto fiber tracts for visualization

[danwu]

Dear experts,

I am trying to map scalar values (fa.nii, mk.nii, etc.) onto the tracts for visualization. I realize .tsf files can be loaded and mapped onto tracts like the screenshot below, but is there a way to map conventional 3D images onto the tracts?

Thanks a lot!

You’re almost there! Take a look at tcksample to map your 3D image… as a .tsf file. You can then load it in the same way as any other .tsf file.
