Hi Allison,
A suggestion is to use the surface area of each hemisphere as the
weighting factor. The global average thickness for both hemispheres is
then given by:
bh.thickness = (lh.thickness*lh.surfarea + rh.thickness*rh.surfarea) /
(lh.surfarea + rh.surfarea).
If you use the data in the ?h
Hi all,
Please pardon the novice question... but what is the best way to get
global mean cortical thickness (i.e. combined across hemispheres)? I
have used mris_anatomical_stats to get mean thickness separately for
each hemisphere. To get a global mean thickness, would I just take a
simple av
Hi Doug,
We have an old EPI data set where automatic (preproc-sess) or bbregister
with any init type give a bad result. Hence, we are attempting to use a
manual register.dat file instead. However, we must be doing something
wrong, because changing preproc-sess to use our manual register.dat (done

Hi Bruce,
My problem has been solved. I rotate the ?h.sphere by mris_rotate
0 0 90 and then I used mris_register to register it to fsaverage
and I saw my result is perfectly registered to fsaverage. it means that
mris_register was not able to realign the sphere to fsaverage if the
