This si Great!!! Thanks Doug. One more question:
What is the correct input in the command mri_surfcluster. Is it the image "sig.mgh" ?
Bests,
John

You will have to extract clusters (mri_surfcluster) to create an
annotation, then use mri_segstats with the --annot option and specifying
the y.mgh file as input and the output using something like --avgwf
output.txt (also add --exludeid 0). The output will have a row for each
frame in y.mgh (ie, each subject) and a column for each cluster
