Hi Amir - Are you using the official 7.1.1 FreeSurfer release or a beta
version? The config file that you are using seems to be newer than 7.1.1.
Please attach your entire trac-all.log file, this will help answer this and
other questions.
Thanks,
Anastasia.

Subject: [Freesurfer] dwi_orig_las issue trac-all -prep
External Email - Use Caution
Dear FreeSufer users/experts,
I am trying to do TRACULA (FS 7.1.1) on a subject with b = 0,1000 in 60
directions. The preprocessing steps of denoising, bias-field, eddy/motion
correction were done using MRtrix (in .mif format) and their outputs are
converted into .nii, .bvec, and .bval. I changed the dmrirc.example into the
attached file to omit the associated preprocessing steps.
Running the trac-all -prep -c dmrirc.pilot results in an error right at the
beginning:
reading info from /<a long path!>/AnalyzeDWI/pilot/dmri/dwi_orig_las.1.nii.gz...
error: niiRead(): error opening file
/<path>/AnalyzeDWI/pilot/dmri/dwi_orig_las.1.nii.gz
It is not present in the output folder.
Interestingly, this file is generated a few lines above and then renamed into
dwi_orig_las and then into dwi.nii.gz:
mv -f /<path>/AnalyzeDWI/pilot/dmri/dwi_orig_las.1.nii.gz
/<path>/AnalyzeDWI/pilot/dmri/dwi_orig_las.nii.gz
A few lines later:
mv -f /<path>/AnalyzeDWI/pilot/dmri/dwi_orig_las.nii.gz
/<path>/AnalyzeDWI/pilot/dmri/dwi.nii.gz
Thus, my guess is due to this renames it cannot find it.
Any help is appreciated.
Bests,
Amir
p.s. the MRtrix-preprocessed file is itself LAS:
orientLAS /<path>/AnalyzeDWI/pilot/dmri/dwi_orig.1.nii.gz
/<path>/AnalyzeDWI/pilot/dmri/dwi_orig_las.1.nii.gz
INFO: input image orientation is LAS
INFO: input image determinant is -8
