I don’t understand how the error could happen, and where ‘if: Expression Syntax.’ comes from. The error was reported from this sections code in fslregister:

set refvol = `stem2fname $SUBJECTS_DIR/$subjid/mri/$fsvol`

if(! -e "$refvol") then

echo "ERROR: cannot find $SUBJECTS_DIR/$subjid/mri/$fsvol"

exit 1;

endif

Can you ‘stem2fname /home/dylan/Documents/TRACULA/INPUTS/BIDS/derivatives/freesurfer/sub-01/mri/brainmask’ from your command line?

Could you point me towards the correct log file? I am unable to locate it at the moment. Also, here are the results of running tree on that directory:

There should be a log for the command you ran.

I’m wondering what your FREESURFER_HOME and SUBJECTS_DIR are. What are the files in /home/dylan/Documents/TRACULA/INPUTS/BIDS/derivatives/freesurfer/sub-01/mri/?

Sure thing, I have attached the two log files i could find at OUTPUTS/sub-01/dmri/xfms/tmp.bbregister.473930. Please let me know if these aren't the correct log files.

The error that you cut and paste here doesn’t show which command it was running.

Can you attach the log file?

Best,

Hello,

I am attempting to create a freesurfer v7.2.0 docker container that can run tracula on the freesurfer outputs, however, I am unable to get past the intra-subject registration step without receiving the following error:

--s sub-01 --mov /home/dylan/Documents/TRACULA /OUTPUTS/sub-01/dmri/xfms/tmp.bbregister.464939/template.nii --reg /home/dylan/Documents/TRACULA/OUTPUTS/sub-01/dmri/xfms/tmp.bbregister.464939/reg.init.dat --niters 1 --maxangle 90 --tmp /home/dylan/Documents/TRACULA/OUTPUTS/sub-01/dmri/xfms/tmp.bbregister.464939/fslregister --dof 6 --fsvol brainmask.mgz --nobetmov

Here is a link to the github page I am using for my custom dockerfile: MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://github.com/lawlessrd/TRACULA_VUIIS.git.

I used neurodocker to combine installations for FSL and Freesurfer. I am using FSL v6.0.0 and Freesurfer version: freesurfer-linux-centos6_x86_64-7.2.0-20210720-aa8f76b. The log output contains the same information as the code linked above.

Machine info:

I have also attached the config file I have created for this test dataset.
