Dear Freesurfers,

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 -per-session. 

The error message was the following : 
......
stc-sess Done

rawfunc2surf-sess -fwhm 6 -s 5167 -d /Applications/freesurfer/sessions -fsd bold -stc down -update

ERROR: could not determine file for /Applications/freesurfer/sessions/5167/bold/007/fmcpr.down
When I use the middle slice as a reference slice with the command -per-run I don't have any problems. 
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?


Cheers,
