Yes, they won't be preserved unless they are 1

It is 5.3.  The voxels erased  was set as 0.  Is that the problem? If so,  I can try to replace 0 with 1.

What version? Check the voxels you erased and see if they were set to 1 instead of 0

Hi Bruce,

Thanks for your response.  the editing was done in freeview. I saved the edited version as wm.edited.mgz, then copy the wm.edited.mgz to wm.mgz.  is that the problem?  Is it necessary to save the edited wm.mgz as wm.mgz in freeview?  I hope it is clear what I did.

Thanks,
Xiaomin

Hi Xiaomin

how did you edit wm.mgz? If within tkmedit (or "recon editing" in freeview)
and you reran recon-all it should have preserved your edits, even though it
regenerated the file. Have you checked?
