Dear FreeSurfer experts:
I have been using FreeSurfer for segmentation and for volumetric analyses. I
want to give a try to use it for surface-based fMRI analyses.
I encountered some issues with mris_preproc to assemble IRF results to the
fsaverage surface. Please advise on how to resolve these issues.
Here is what I did:
After finishing "recon-all" on each subject, I ran this following on each
subject.
bbregister --mov reg_cat_TSall_before_blur.nii --bold --s freesurfer --init-fsl
--lta register.lta
"reg_cat_TSall_before_blur.nii" is the EPI fMRI time series assembled together.
Then I calculated the IRF percent signal changes for different conditions.
"sum_all_norm_IRF_EA.nii" is for one condition.
Now I want to assemble the "sum_all_norm_IRF_EA.nii" from each subject and put
them on the fsaverage surface. I got the following errors:
