Hi,

Again me... in our lab, there is a problem in how the bvalue are reported in the dicom header, even thought the first 5 volumes are without gradiet in the bval  file that come from dicom2nii the first 5 entries are "1000" rather then "0"and I have to manually substitute the first five entry with five "0", however I was told that the bvecs were ok, at least for the analysis in FSL.

Now given the problem that I had and given your suggestion, I changed also the bvecs following your indication and I ensured that this would not effect the analysis in FSL by controlling the value of FA (in exactly the same point) obtained after DTIFIT with the bvecs modified and again with the bvecs not modified. Given that the data were exactly the same, I run again the pipeline with PANDA with the Bvecs that you suggest, in order to finally obtain both the probabilistic and the deterministick tractography to do network reconstruction in both ways.

Now I had no error messages, no failed jobs, the pipeline is finished, but the problem is that the ProbabilisticMatrix_OPD_1.txt file is empty.

You think this modification to the bvecs could affect someting in the probabilistick tractography, and Why there are no failed jobs?

Attached is the pipeline history,

Best,

Mauro
