Corrected p-value on cortex


Based random field theory, multiple comparisons can be done. The p-value after multiple comparisons correction is usually referred as the corrected p-value. It computes p-values on triangular meshes that is topologically equivalent to a sphere. It has been applied to both the human cortex and the human hippocampus surface.


MATLAB Codes (MATLAB 6.1. implementation)

This is modified from Keith Worsley's original fMRIstat package. 

The corrected p-value can be computed on the following sample cortical surface. 

trisurf(tri, coord(1,:),coord(2,:),coord(3,:));
