Hi – I’m doing manual edits in tkmedit.  In the tkmedit “working with data” page on the wiki, it states that there are three ways to “undo”, one taking advantage of the “undo volume.”  The instructions say to select View->Undoable voxels, then use the shift key and mouse button 2 with the edit voxel tool active, the voxels will be returned to their original values.  I have the latest version of freesurfer, and there is no “undoable voxels” in the view menu.  I can view edited voxels.  However, nothing is undone when I hold the shift key.  Under edit, however, there is an option to “clear undo volume” which makes me think that the undo volume still exists.  Is this still an option for editing? 

Thanks,

Allison
