My problem is I need to change the dimension of the image .Now it is 39*305*305. ie number of slices 39. So i need to change the dimension as 305*305*39. I do X and Y rotation using M=[0 1 0;1 0 0;0 0 1] nii_reorient(“Sub.nii”,M) //SPM script then I do Y and Z rotation using M=[1 0 0;0 0 1;0 1 0] nii_reorient(“Sub.nii”,M) Now dimension is changed to 305X305x39 .but when I viewed this from MRIcron, axial one becomes sagittal.
