Dear Freesurfers,<div><br></div><div>I ran into an issue while trying to
 preprocess some resting state data. As I wished to use the first slice 
to correct for motion, I typed in this command : preproc-sess -s 5167/ 
-fsd bold -stc down -surface fsaverage lhrh -mni305-2mm -fwhm 6 -<b>per-session. </b></div><div><br>The error message was the following : </div><blockquote cite="mid:7250e8d3132c.4ecfabee@unige.ch" class="iwcQuote" style="border-left-width: 1px; border-left-style: solid; border-left-color: rgb(0, 0, 255); padding-left: 13px; margin-left: 0px; " type="cite">

<div>Does
 any one know where this is coming from? I see some people already had 
the same issue a while ago,  does any one know if a solution was found?</div><div><br></div><div><br></div><div>Cheers,</div>Elisa Scariati
