Dear Community,
I have just downloaded Mrtrix3 to run some tractography analyses.
Reviewers of my data have suggested me to compare the performace of Mrtrix3 using spherical deconvolution (SD) and a “simply” deterministic algorithm for reconstruction of cortico-spinal tract with the probabilistic analysis I run (using bedpostx). I use a clinical scanner (bvalue=900 s/mm2, 25 diffusion gradient directions).
I run dwi2response
on nifti data, then dwi2FOD
obtaining my SH image which seems ok, since I then performed the tckgen
reconstruction with the default algorithm option iFOD2
and the tracts look ok.
Trying tckgen -algorithm tensor_det -fslgrad bvecs bvals
with all ROIs option and giving as input the SH.nii.gz file, returns to me an error: "error importing diffusion gradient table for image “SH.nii.gz” ".
Is it possible to perform determinist reconstruction of the tract using a processing line like that I thought?
Thank you for your help
Claudia
