Hi everyone!
I‘ve been used fmriprep tool kit to preprocess BOLD signal. After that,I tried to open outputs files 'L/R_fsaverage5.gii' on freeview.
I firstly loaded surface files 'fsaverage5/rh(lh).inflated', then I overlayed the 'L/R_fsaverage5.gii' on the loaded surface. However, I encountered a problem that half of the vertives on the brain have a null value (no color showed on these vertices).
I was expected the surface and overlay to look like 1.png. But they look like 2.png now.
If anyone know the reason of these null value and how to fix ti? I would be grateful for any help anyone could give me!
