External Email - Use Caution Dear freesurfer developers and Dr. Yendiki,
I am trying to run trac-all -prep -c dmriEla, dmriEla being my config file. I am attaching the config file here. If I perform registration-based correction with eddy_correct, doeddy=1, things start to run. However, if I use doeddy=2, model-based correction with eddy, 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 No Trac-all.log file is created. If needed, I can also send you a few anonymized slices from the acquired DTI series, so you can check the header. Moreover, I can send you the acquisition sequence properties as a PDF file if needed. Is there a way to fix this problem? In other words, can we do something to be able to use model-based correction instead of registration-based questions since it seems to be a more sophisticated method? I'm running freesurfer on Linux Centos7, the version of freesurfer is 7.2.0 and the installed package is freesurfer-linux-centos7_x86_64-7.2.0.tar.gz. I really do appreciate your time and help. Ela
