[Freesurfer] extracting time courses from fMRI

2011-12-09 Thread Hellyer, Peter 
Hi All,

I'm trying to extract time courses from functional data

I started by registering my motion corrected functional data to my segmentation 
using bbregister, then I used:

mri_vol2surf --src Motioncorrectedfunctional.nii.gz --srcreg register.dat --out 
suface.mgz —hemi rh 

mri_segstats --in surface.mgz --annot subject rh aparc --sum sum_output --avgwf 
Timecourse_output

Is this a sensible thing to do?  I'm not particually sure about the 
mri_vol2surf step..

Thanks in advance.

Pete
