Voxel Edit
The Voxel Edit mode in Freeview includes tools which can be used to remove, add or alter the value of voxels in volumes loaded into Freeview. You can create custom labels or an entire manual segmentation composed of many regions with custom names. The Voxel Edit tools can be used to make typical Freesurfer edits to correct surface topology and segmentation errors, but we recommend you use the Recon Edit mode instead which has all the tools listed below but with certain restrictions implemented to insure recon edits are recognized by recon-all. Please read the ReconEdit page for more details on the restrictions implemented to the tools described below.
The voxel edit mode is located just above the layer list and underneath the menu bar, or can be found under Action -> Voxel Edit in the menu bar. Alternatively, you can use the shortcut key Alt+E.
