[Freesurfer] unable to map surface to fsaverage4

External Email - Use Caution

Hi,

I'm following the process described in https://www.cloudneuro.org/ to predict age based on cortical thickness of an individual brain. I cannot map surface to the fsaverage4 template by the 2nd command: recon-all -s subject.id -qcache -target fsaverage4The error was shown like mri_surf2surf: could not read su​rface ./test2/surf/lh.fsaverage4.sphere.regNo such file or directory

I tried to change the 1st command like: recon-all -i input_image -s subject.id -all -target fsavearge4But still the same error.

My FreeSurfer version is 6.0.0. Maybe that's why I cannot successfully run the code in https://www.cloudneuro.org/. But is there any way to solve this problem? Thank you.
