Greetings. I want to fiber tractography using mrtrix. I am specifically interested in visualizing corpus callosum tracts. I want to compare the tracts for visualization (ground truth tracts for b = 2000 shell data from the hcp dataset with my predicted b = 2000 tracts from a reconstructed data).
Basically, i want to compare tracts like the one shown above.. So far, I have obtained the white matter fodf map and generated white matter tracts like below (shown in coronal view)…
There are many atlases available in MNI space, and many will include parts of the corpus callosum (I know the Harvard atlas that comes with FSL has it). I would warp these ROIs into T1 space nonlinearly, then affine into DTI. You can use tckedit to extract streamlines based on whether they pass through the ROIs, which should give you your desired streamlines.
