External Email - Use Caution

Hi Experts,

I have a set of resting state data in nifti format. I want to get these data into gifti format, so I can then convert them into cifti format and run melodic ICA. I suspect using mri_vol2surf would do the trick, but I know you need to specify which hemisphere you want the projection to take place on. However, I wondered if it was possible to do this for both hemisphere, or whether there is a command to merge the two hemisphere back together into a single gifti file after running vol2surf separately? The command I am currently running is:

Mri_vol2surf –src filtered_func.nii.gz –out resting_surface.gii –srcreg partial-to-struct.lta –hemi lh –projfrac 0.5 –out_type gii

Any advice would be great. Thanks, Mason
