Hi Subha, there are tools to do this in FS. You can use mri_vol2surf to
map your time courses to the surface and save the output as a gifti (eg,
mri_vol2surf --mov f.nii.gz --reg register.dof6.dat --hemi lh --o
junk.gii --projfrac 0.5)
Or you can use the FS functional analysis stream (FSFAST). Tutorial is here:

Hello All,
I have run recon-all on some subjects. I have functional BOLD data on
these subjects too. I am doing fmri preprocessing in spm. I have
created register.dat by registering the meanBOLD image to the
freesurfer reconstructed data. I am intending to do the following -
I want to take each functional volume corresponding to each TR and
move each volume to freesurfer and make a BOLD surface file in
freesurfer (.mgh file).
Then I want to run first level glm on the data like its done for
volume data in spm, fsl, afni etc.
My question is are there tools in freesurfer to do this on surfaces ?
If not, can the mgh file be converted to a gifti file and maybe it can
be used to make first level glms in afni, spm or fsl ?
I will really appreciate your opinion about this.
Thank you very much,
Subha
