In case anyone wish to perform a multiple comparison on the cortex, I have written a MATLAB function that gives the threshold for t statistic: http://www.stat.wisc.edu/~mchung/softwares/pvalue/pvalue.html
You need to compute the area of all triangles by yourself to be put into the MATLAB function and requires some sort of surface-based smoothing that controls the amount of FWHM. The detail can be found in http://www.stat.wisc.edu/~mchung/papers/ni_heatkernel.pdf Moo. -- Moo Chung http://www.stat.wisc.edu/~mchung Assistant Professor Department of Statistics University of Wisconsin-Madison _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
