Hi Rafael,

Is your subject directory stored on an external drive like an SD card? The 
“Function not implemented” error implies that symlinks are not supported on the 
filesystem that you’re saving to. Ubuntu 18 definitely supports symlinks and I 
see that SUBJECTS_DIR points to /media/rafa…. You should process your data on 
the ubuntu filesystem first, then try copying it onto a card after.

Best,
Andrew

I was trying to run the command:  recon-all -s bert -all

It ran for hours, but finally output the following:

writing Gaussian curvature to ./lh.white.preaparc.K...done.
writing mean curvature to ./lh.white.preaparc.H...done.
rm -f lh.white.H
ln -s lh.white.preaparc.H lh.white.H
ln: failed to create symbolic link 'lh.white.H': Function not implemented
