pTFCE for vertex-wise cortical surface data #21

Open CogBrainHealthLab opened 1 week ago

CogBrainHealthLab commented 1 week ago

Hi this is not really an issue, but i was wondering if its possible to implement pTFCE for vertex-wise cortical surface data (e.g., FreeSurfer surface output), where the vertices on the cortical surface are mapped onto a 1-dimensional array.

Unlike 3D volumes/matrices, in this vertex-wise cortical surface context, the cluster size is determined by counting the number of connected suprathreshold vertices. Whether a vertex is connected to another is in turn determined with reference to an edgelist that is provided by the user. This edgelist is a E x 2 matrix , that list down every pair of connected vertices

vertexTFCE for CIVET-style surfaces is available here, might be of use https://mouse-imaging-centre.github.io/RMINC/reference/vertexTFCE.html
