Hi Francois,
that was my mistake, I think I misread this post (Statistics on sources) and did not see the option checked 'use absolute values' in the smoothing option, and thus thought smoothing was done prior to the rectification. So my workflow now is:
- normalized with Z-score with respect to the baseline (no absolute value)
- I then rectified (absolute value) each individual's file
- I then projected each individual's rectified source file to the template anatomy
- applied the default smoothing option to each individual's average file
- I then use these resulting files (under the the 'intrasubject' tab) for statistical testing (two groups; independent t-tests in my case).
That looks to be similar to the workflow page.
Thank you again!
Paul
