I would like to apply dynamic causal modelling analysis to surface based
data, and I posted other several related questions before. I am a newbie to
FreeSurfer. According to my understanding, the normalization in FSFAST
should take the advantages of str
why not just map the fmri volume into the anatomical volume
(mri_vol2vol)? Why go through the surface at all?

Refer to my previous question. I found that 'vlrmerge' could be used to
visualize the whole brain activation through mapping the left and right
surface to the volume. But the data generated by vlrmerge cannot be used
for analyzing. Hence I am wandering

Sorry for my confusing explanation. I mean cortical grey matter. How could
I map the left and right surface fmri data to volume? For example, how to
transform the preprocessed left surface data
'fmcpr.odd.sm5.fsaverage.lh.nii.gz' to 3D volume?
Thanks,
you mean just subcortical gray matter? You could map the aseg into the
functional space with mri_label2vol (run with --help to get docs and
examples). Then mri_binarize --i aseg.func.nii.gz --subcort-gm --o
subcortgm.mgz, then mask the fmri time series (fmcpr.nii.gz) using mri_mask.

I see and thank you very much. May I know If I could transform the
surface-based time series data to volume space, like the space of
subcortical data 'fmcpr.odd.sm5.mni305.2mm.nii.gz'? I know I could get the
whole brain 3D volume fmri data by changing t

Dear Freesurfer experts,
I would like to transform the task-based surface data to volume. May I know
if it is applicable? I tried "mri_surf2vol --o test.nii.gz --subject sub002
--so fs/sub002/surf/lh.white
