Freesurfer distributes ‘fsaverage’ under $FREESURFER_HOME/subjects directory. 
recon-all should create symbolic link to $FREESURFER_HOME/subjects/fsaverage 
under $SUBJECTS_DIR.

This is from your recon-all.log
“
setenv SUBJECTS_DIR /usr/local/freesurfer/subjects
FREESURFER_HOME /usr/local/freesurfer
Actual FREESURFER_HOME /usr/local/Freesurfer
“

You are setting SUBJECTS_DIR to your Freesurfer install directory. It is a good 
idea to set SUBJECTS_DIR to some other directory that you have write permission.

Your recon-all failed because of “Too many levels of symbolic links”. Can you 
check what you have under $FREESURFER_HOME/subjects?
>ls -l $FREESURFER_HOME/subjects

You should have these in the directory:
drwxrwsr-x. 2 zkaufman fsbuild    4096 Mar 13  2012 cvs_avg35
drwxrwsr-x. 2 zkaufman fsbuild    4096 Apr 14  2015 cvs_avg35_inMNI152

drwxrwsr-x. 2 zkaufman fsbuild    4096 Nov 11  2008 V1_average

Your recon-all should have created this link ‘fsaverage -> 
/usr/local/freesurfer/subjects/fsaverage’ in the directory as well. Remove 
link. Set SUBJECTS_DIR to some other directory and restart recon-all.

Best,

Yujing

Hello FreeSurfer Developers,



I'm attempting to run recon-all command, but  I get the following error when I 
run the "recon-all -i sub.mgz -s sub1 -all" command:



ERROR:

recon-all -s my_sub exited with ERRORS at Fri Nov 24 23:43:39 IST 2023

Does anyone have any thoughts on how to trouble-shoot this one? I've attached 
the recon-all.log.
