For any of the import options above, after clicking the 'Start' button, first you will be asked to select the GIFTI file.
Import of map: The third option enables the import of statistical data (*.func.gii) to BrainVoyager surface maps (*.smp). When the intent is larger than NIFTI_FIRST_STATCODE and smaller than NIFTI_LAST_STATCODE (extension is usually *.func.gii), the file will be converted to a BrainVoyager statistical surface map (*.smp).
Import of labels (or poi): The import of labelled data (for example atlases) (*.label.gii) to BrainVoyager patches of interest (*.poi) is possible via the fourth option. These data may be sparse or not sparse. Please note that if the BrainVoyager surface file is currently opened, the plugin will assume that the imported label file belongs to this surface.
Print info to logtab:This option is checked by default. It will write header information of the file that should be converted to the BrainVoyager QX log tab. Also, it will display information concerning the conversion procedure in the BrainVoyager QX log tab.
Reverse triangle winding: When the surface looks half transparent and looks fragmented (see picture below), then use the option 'Reverse triangle winding'. This is only applicable to surface files.

In case the label file is sparse, the plugin will read the number of vertices of the current surface. Otherwise, a file dialog will ask for the name of the BrainVoyager surface file where this *.poi file belongs to. If the parameter "number of mesh vertices" in the *.poi file is not equal to the number of vertices of the currently opened mesh, the *.poi file will not load.
The imported file is located in the same directory as the original GIFTI file.
Options
Open in BrainVoyager:When this option is checked, and the required underlying files are open in BrainVoyager (usually an anatomical image (*.vmr), and for mesh time courses (*.time.gii), maps (*.func.gii) and label files (*.label.gii) also a surface), the imported file will show directly in BrainVoyager.
Add colors to surface: If you have a file that provides labels and colors to different brain regions, the colors can be imported and used as mesh colors. This option will first ask for the GIFTI surface file, then for the GIFTI label file (*.label.gii). Please note that the labels and colors file can also be imported as patch-of-interest (*.poi), which will preserve both colors and labels.
