hi there, <br><br>i noticed a strange problem tonight. I had a .nii.gz file. I used mri_convert to convert it into a .mgz file. I also used gzip to unzip the .nii.gz file and then used mri_convert again to get another .mgz file. But the two .mgz files have different md5 sums. Does anyone know what caused the problem? Or is there a problem? <br>

<br clear="all">Cheers, Forrest<br>
