Hi Falk,

what about you change the voxelsize to 1 mm before opening the volume in tkmedit for modifications and then change them back to the original values after you are done. I have not tried that, but it should work at least around the tkmedit problem...

As mentioned in the first email somehow tkmedit seems to skip some slices if one tries to edit them manually and the resolution of the volume is not 1mm^3. Attached is a screenshot of the filled.mgz which I tried to edit on the left from the coronal view and on the right from the sagittal view.

The resolution of the volume used in this case is 0.6mm. If I use the "Slice" thing to browse through the slices nearly every second slice is skipped. Increasing or decreasing the volume index by 1 in the direction I would like to move on doesn't work either. For example if I change the volume index from 162 338 124 to 163 338 124 the same slice is being shown. 161 338 124 and 164 338 124 are different as it should be, but it is not possible to view 163 and so it is impossible to edit this slice.

Are there any other tools available to edit volumes like tkmedit does? It doesn't need to be included within FreeSurfer but it would be better if it could handle the .mgz format.
