Web5 Apr 2024 · The white matter probability mask was smoothed using a three-dimensional Gaussian kernel with a full width at half maximum of 3 mm to mitigate partial volume effects [ 31, 39 ]. A joint gray and white matter mask was thereafter created at a threshold of 0.9. WebAfter you have created your mask, you may want to convert it from the .mgz file type to .nii (.gz) if you wish to use your segmentation in other software, such as FSL or SPM. To do this, you can use the Freesurfer function mri_convert. For example, to convert the Left-CM mask from the above example, you would use the following command:
