Hi Freesurfers,<div><br></div><div>The selxavg3-sess&#39;s help and Freesurfer documentation say that selxavg3-sess creates a design matrix for each run, fits the glm for each run, and then combines the runs together to give summary data for the subject&#39;s whole session.  Some of the fsfast 5 slides say it uses &quot;smart&quot; concatenation to combine each run&#39;s data -- what is &quot;smart&quot; concatenation?  How does are the runs brought into alignment?  </div>
