Hi all, 

 

I am trying to run trac-all -prep -c dmrirc1.txt, with dmrirc1.txt being the configuration file. As soon as I attempt, I get the following error:  

  

 

ERROR: for B0 distortion correction with reverse-polarity DWIs  

ERROR: or for model-based eddy-current distortion correction,   

ERROR: must specify PE direction 

 

 

I am attaching the dmrirc1.txt to this message.  

  

The FreeSurfer segmentations of T1, produced by running Freesurfer recon-all, was done using freesurfer version 6. We try to run trac-all using freesurfer version 7.2.0.   

Interestingly, we don’t face the same error when we tried running trac-all using version 6 of freesurfer.  

Lastly, it is worth mentioning that no dmri folder has been made after running trac-all, and there is no trac-all log file in the script folder.   

  

1) FreeSurfer version: freesurfer-CentOS7-7.2.0-1.x86_64.rpm.  (Build-stamp text: freesurfer-linux-centos7_x86_64-7.2.0-20210720-aa8f76b)  

2) Platform: CentOS7 

Thank you and Kind regards,
