Thanks Bruce. You are right. mri_diff gave nothing on the Shell. So, i don't have to worry.

Cheers, Forrest

try running mri_diff on them. The image data should be the same. It's probably the difference between the command line gunzip and the libraries

hi there,

...

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?

Cheers, Forrest
