As the goal of the present method and toolbox is to retrieve channels as output of selected regions of interest, results have been grouped by landmarks, thus enabling look-up tables from anatomical landmarks of interest. An example is shown in Table 3 for landmark “Precentral_L” as defined in AAL2 and resulting channels information (source, detector and MNI coordinates).Table 3Example of channels with at least 10% specificity of “Precentral_L” (AAL2).SourceDetectorSpecificity (%)Distance (mm)XYZC3FC354.1237−50−350C3C149.3840−42−2062FC5FC342.4436−551234FC1C135.8839−26−568CzC131.8939−17−2074FC1FC321.1036−381255FC5C516.6633−62−323CP1C115.6439−27−3671The inter-optode distances according to positions on Colin27 are provided.
