Hi Arash
have you registered them? You can reslice the wm.mgz to have the same voxel geometry as the flair using
mri_convert -rl flair.mgz wm.mgz wm.resliced.mgz
but only if they are in register. Otherwise you need to apply the registration transform as well, which you can also do in mri_convert with -at <transform name>

Hi, I would like to apply white matter mask (wm.mgz) produced by freesurfer recon-all command on FLAIR. The FLAIR and wm.mgz have different dimensions such that Flair is 512by512 while wm.mgz has 256by256 in dimensions. I tried to fix this by resizing the flair in matlab but after applying the mask the result is not good. I don't get the difference in dimension anymore though.
Is there any way that I can resize a mgz volume in freesurfer?
Many thanks, Arash
