02/03 Feb 2017
- Projection of grid electrodes to SCE (convex hull) sourface
- Automatic check for new updates
- Load ch labels from EEGLAB .set files
- Load ch label from .edf (EEG) files
- Save electrode coordinates in EEGLAB or Fieldtrip format
- Small bugs corrected for compatiblility with MATLAB 2013a
- 2 new tutorial datasets are provided. One dataset is in native space and the other one in normalized space. Go to the Files menu, navigate to example_datasets folder and download the latest version.

24 Oct 2016
- Indexing step added (Now is 1st numbering and then labelling )
- lines between electrodes added in 3D view
- HO atlas working on non- 1mm isotropic images
- find corners method improved for deformed grids. This is part of the nubering method.
