External Email - Use Caution

I was able to circumvent the error by switching from python3 to python2.

In python3 print was changed to a function making it necessary to put the arguments in brackets.

External Email - Use Caution Dear Juergen,

Thanks for your quick reply! Actually the spelling error is in the error message. Taken from http://martinos.org/~mreuter/long/long_mris_slopes

# extensive error checks # if options.fsgd is None and if options.qdec is None: # print 'ERROR: Specify --fsgd or --qedc' parser.print_help() print '\nERROR: Specify --qedc (and other required arguments)\n' sys.exit(1)

# if options.fsgd is not None and options.qdec is not None: # print 'ERROR: Specify either --fsgd or --qedc, not both' # sys.exit(1)

At least Martin is consistent with his typo. :D

Best, Falk

I have no idea, but recognised that the error refers to --qedc and not to --qdec. maybe there is a spelling error somewhere that is related to your problem.

Dear all,

Has anyone run the longitudinal pipeline successfully using the WSL? I’m running it with Ubuntu 18.04.1 LTS and freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c.

I’m trying to process my first longitudinal data set following the instructions of the tutorial as close as possible. The data has been processed without issues and now I want to do the statistical analysis. When I run: long_mris_slopes --qdec ./long.qdec.table.dat --meas thickness --hemi lh --do-avg --do-rate --do-pc1 --do-spc --do-stack --do-label --time years --qcache fsaverage --sd $SUBJECTS_DIR

I get the following error: File "/home/luesebri/Software/FreeSurfer/bin/long_mris_slopes", line 448 print '\nERROR: Specify --qedc (and other required arguments)\n' ^ SyntaxError: invalid syntax

I get comparable errors for any other long_* command I try to run, e.g. long_qdec_table with or without any arguments gives: File "/home/luesebri/Software/FreeSurfer/bin/long_qdec_table", line 119 print '\nERROR: Specify --qedc' ^ SyntaxError: Missing parentheses in call to 'print'. Did you mean print('\nERROR: Specify --qedc')?

Does anyone have a clue where this error originates from using either WSL or Ubuntu 18.04?
