Hello,
I was wondering what the best way would be to extract the coordinates of each voxel in my nifti volume in mm. I have used MRIread to load the nifti volume into Matlab (=mri) and wanted to essentially create a new variable that takes each (voxel) entry in mri.vol and exports its three coordinates in mm. Would I just need to multiply the mri.vox2ras 4x4 matrix to each voxel’s [X Y Z 1]’ (where X,Y,Z are the voxel’s coordinates in mri.vol) or are there different steps involved?
Thank you in advance for your time and help!
Best, Panos
