Hi!
For my research I need to map FA profile of a volume to the interested tracts. Actually I have a .tck file generated with tckgen command which then I extract my desired RIO and save always as a .tck file. Now I have the coordinates of different pieces of each tract in millimeter. Beside I have FA map in .nii file. Now I need to read the intensity of each piece of my tracts (in .tck file) from my .nii file. But I can not find no way to access the coordinates of my .nii file. There are only corner coordinates and voxel size in .nii and with these informations I can not find any point in my .nii which correspond to my .tck points.
I am blocked for one week to find a way and I would highly appreciate your indications.
