Dear Freesurfer support,

I am very new to freesurfer and I thank you in advance for your assistance. I have been trying to run the group analysis tutorial (qdec) and I have encountered the following error messages. I was unable to generate the stats data tables in the tutorial and received the following types of error messages:

1) When trying to run asestats2table in qdec I get an error message that says that the subjects are not specified although they are. The $SUBJECTS_DIR is correct. I even encounter the same error when I just try to run asegstats2table --help (see below):

tegmentum:group_analysis_tutorial gazzlab16$ asegstats2table --subjects 004 045 091 --meas volume --tablefile aseg_stats.txt
  File "/Applications/freesurfer/bin/asegstats2table", line 186
    print 'ERROR: subjects are not specified (use --subjects SUBJECTS)'
                                                                      ^
SyntaxError: invalid syntax

tegmentum:freesurfer gazzlab16$ asegstats2table --help
  File "/Applications/freesurfer/bin/asegstats2table", line 186
    print 'ERROR: subjects are not specified (use --subjects SUBJECTS)'
                                                                      ^
SyntaxError: invalid syntax

2) When trying to run asestats2table I get an error message that says that at least one subject must be provided although they are. The $SUBJECTS_DIR is correct. I even encounter the same error when I just try to run aparcstats2table --help (see below):

tegmentum:group_analysis_tutorial gazzlab16$ aparcstats2table --subjects 004 045 091 --hemi rh --meas thickness --tablefile aparc_stats.txt
  File "/Applications/freesurfer/bin/aparcstats2table", line 151
    print 'ERROR: atleast 1 subject must be provided'
                                                    ^
SyntaxError: Missing parentheses in call to 'print'
tegmentum:group_analysis_tutorial gazzlab16$ aparcstats2table --help
  File "/Applications/freesurfer/bin/aparcstats2table", line 151
    print 'ERROR: atleast 1 subject must be provided'
                                                    ^
SyntaxError: Missing parentheses in call to 'print'


I am not sure how to proceed. Thank you again for your assistance.

Sincerely,
Elissa
