Hi Konstantina, you have to set SUBJECTS_DIR equal to an actual directory path in your filesystem, the “<path to subject directory>” is just a placeholder.

Best,

Hi Bruce,

I managed to overcome said error but now during example 2 another error pops up. 

Skol-MacBook-Pro:~ kskol$ export SUBJECTS_DIR=<path to subject directory>

-bash: syntax error near unexpected token `newline' 

Thanks,

Konstantina

Hi Konstantina

do you have write access to the partition you are putting the subjects_dir
on? And can you please send us the full command line, screen output and
recon-all.log?

cheers
Bruce
