after a partial correlation (cortical thickness in different brain regions of 24 Subjects correalted with socres on different neuropsychological scales) I tried to define the minimal and maximal cluster size in Qdec in order to show only the largest effects. I run "mri_surfcluster" and other commands described on
. Unfortunately, it did not work. Should I use all the command lines? What is exactly meant by "inputfile" and "csd csdfile"? I guess my inputfile should be the "table.dat" File and T1-weighted images of all 24 Subjects...?
