Hi list,
I'm performing FS-FAST on rsfMRI.The seed is MRS voxel.I have run:
1-mri_convert MRS_MASK.nii.gz $SUBJECTS_DIR/MRS_MASK.mgz 
2-fcseed-config -segid 1 -seg MRS_MASK.mgz -fsd rest -mean -cfg 
mean.MRS_MASK.config
3-fcseed-sess -sf sessid -cfg mean.MRS_MASK.config
4-      mkanalysis-sess -analysis fc.MRS_MASK.surf.lh -surface fsaverage lh 
-fwhm 5 -notask -taskreg MRS_MASK.dat 1 -nuisreg vcsf.dat 5 -nuisreg wm.dat 5 
-polyfit 5 -nskip 4 -mcextreg -fsd rest -TR 1.1 -per-run      mkanalysis-sess 
-analysis fc.MRS_MASK.surf.rh -surface fsaverage rh -fwhm 5 -notask -taskreg 
MRS_MASK.dat 1 -nuisreg vcsf.dat 5 -nuisreg wm.dat 5 -polyfit 5 -nskip 4 
-mcextreg -fsd rest -TR 1.1 -per-run                      mkanalysis-sess 
-analysis fc.MRS_MASK.mni305 -mni305 -fwhm 5 -notask -taskreg MRS_MASK.dat 1 
-nuisreg vcsf.dat 5 -nuisreg wm.dat 5  -polyfit 5 -nskip 4 -mcextreg -fsd rest 
-TR 1.1 -per-run
5-      selxavg3-sess -sf sessid -a fc.MRS_MASK.surf.lh selxavg3-sess -sf 
sessid -a fc.MRS_MASK.surf.rh selxavg3-sess -sf sessid -a fc.MRS_MASK.mni305
When I performed selxavg3-sess -sf sessid -a fc.MRS_MASK.surf.lh
I obtained this error:
$Id: fast_selxavg3.m,v 1.100.2.2 2012/11/30 18:40:38 greve Exp $

outtop = /Applications/freesurfer/subjects
Extension format = nii.gz

ERROR: fast_selxavg3() failed\n
PLEASE NOTE: MRS_MASK.dat is lacking in Sess101/rest/001. It is present only 
MRS_MASK without extension.
Thanks,

Stefano
