Is there any command that used to generatewhite matter mask based on a T1 weighted image (or based on other parcellation images) in Mrtrix?
I found it that there’re two commands associated with mask generation.
dwi2mask— It is used to generate a whole brain mask from a DWI image.
5tt2gmwmi— Generate a mask image appropriate for seeding streamlines on the grey matter-white matter interface
For Mrtrix is able to create GM-WM Interface, there should have some methods to generate WM mask based on a T1 image.
dwi2response dhollander is able to estimate of WM, GM, and CSF response functions; does not require a T1 image (or segmentation thereof). There may have some method to estimate WM mask without a T1 image.
Does anyone have ideas?
