Hi Experts,
This question may have been addressed elsewhere on the list, but I can’t find a response.
I want to smooth BOLD data on the surface. First, I pre-processed the data in FEAT with no smoothing applied. Then I registered the filtered_func data to the anatomical using bbregister. I check the registration matrix looks good by running this command (using example_func as the reference):
* tkregisterfv --mov example_func.nii.gz --reg junk.dat --lta reg/freesurfer/anat2exf.register.dat --surfs
I then resampled my data with mri_vol2surf using the following command:
* mri_vol2surf --src filtered_func_data.nii.gz --out lh_func_native.mgh --srcreg reg/freesurfer/anat2exf.register.dat --hemi lh --projfrac 0.5 --out_type mgh I then want to smooth this data on the surface. I assume it would be best to run mri_surf2surf and set the target and source subject as the same? Such as this command:
* mri_surf2surf --srcsubject sub-0006 --srcsurfreg lh.sphere.reg --trgsubject srcsubject --trgsurfreg sphere.reg --hemi lh --sval lh_func_native.mgh --tval lh_func_native_smoothed.mgz --mapmethod nnf --fwhm 5 --cortex
Please can someone on this list give me some advice on this? Are my command suitible and/or am I missing anything?
Best wishes, Mason
