Hello,

I have two questions about surface-based analysis in Freesurfer space (Freesurfer structural images, same subject-space functional images), as I need to map functional images after denoising/filtering/acompcor steps from surface to volume for additional analysis (I guess they are are surface-based after these steps). 

1) In /results/preprocessing I found some nifti files named "niftiNORMS_Subject_0*_Session*.nii". Are these the functional files I'm looking for? 

2) Do you know how I can map these files from surface to volume? 

Best,
Lorenzo
