oh, sorry, I thought you wanted to look at the script itself. The .mgh
files are binary files with pixel data. You can view them with
tksurfer/freeview. You can load them with MRIread.m in matlab

Dear Doug,
These files typically end with .mgh. I tired opening them with text
editors and them typically give a file of unreadable characters like:
@&?9<?,@!?@ ^@$?@?@.?@6%@.?@*>?!?@+?@!?@3?@
?@EUR?7]@>?@<E?%N(?????]Z@??@0MU@'? @+?@2Pq@%?@7?@*y7@
?@,?y@
Sincerely,

Hello Freesurfers,
Is there a way that I can take a look at the content of the
output of "mris_preproc"?
Thank you very much!

It resamples them to a common space (the "average"
subject) but does not average them together. The result
is a "stack" which is a single file with multiple subject
it in it ready for GLM analysis

Dear Doug,
Thank you, but I am only more confused after reading the
summary. The summary basically reaffirms my
understanding that "mris_preproc" gives "an average
subject". How can this be an appropriate "data" for GLM,
which for sure needs multiple data points?
Thank you!
Sincerely,
Ye

Hi Ye, have you looked at the mris_preproc help? You
can access it with mris_preproc --help. Let me know
if that does not answer your questions

Hello Freesurfers,
I understand that the output of "mris_preproc" can
be the input of "mris_glmfit". In mris_glmfit, a
GLM is performed.
Does "mris_preproc" give you a smoothed average of
all the subjects?
If that's the case, how can you perform a GLM with
just the average? Don't you need the data (smoothed
or not) of all subjects?
Thank you very much!
Sincerely,
Ye
