why do you want to conform it?

Actually, I also noticed that when mri_convert runs, it says something like "changing data type from 3 to 0 " The data type of the nii file is float32, while the converted .mgz id uchar, is it the problem?
Thanks Guang

Hi, there,
I got a question about mri_convert. I have a brainmask.nii file, (max intensity value is 64, and minimum intensity is 0), it shows good intensity contrast. Now I want to use mri_convert to convert it to mgz file, my command line is
mri_convert A.nii --conform A.mgz
Now, I open A.mgz using Tkmedit, I can not see those significant intensity contrast now, and the max intensity value is 255, and minimum intensity is 0 It looks like mri_convert do something like histogram equalization or normalization.
Will mri_convert actually change the intensity value of each voxel? Can I keep my original intensity value for each voxel? Use the mri_convert -sc?
Thanks a lot!
Guang
