External Email - Use Caution

My bad, I meant to say surfaces. Right now the files are downsampled on fsaverage4 space and I need to now split it into the respective left/right hemispheres. For context, these are .nii.gz files currently. Is there a way to easily do this in Freesurfer?

Subject: Using mri_surf2surf to split files

Hi FreeSurfer developers,

I have preprocessed files in single niftis and would like to split the data for each file into left and right hemispheres to run it through a specific toolbox. It seems like there should be a way to run mri_surf2surf or another command to just split it into 2 hemispheres, what would you all recommend for this?

Thanks.
