Dear all,
Is TRACULA able to handle 4D FSL niftii as input for DTI images? Are
bves/bvalues extracted by dcm2nii and MRICro accurate for TRACULA? I think
TRACULA needs the bvecs in the image coordinate system, which is not the
same as scanner coordinate system in case of oblique acquisition. Do I
Hi Gabor - The input DWIs can be in any format that can be read by
mri_convert, including the NIfTI format. The gradient directions should be
in voxel coordinates, like the ones used by FSL. I don't have experience
with dcm2nii, but if you have original DICOM files, you can pass those as
the
Dear Anastasia,
I've the original DICOM files, but it is acquired with the standard Siemens
DTI ep2_diff, and not with the MGH-DTI sequence. Is DTI images acquired
with the standard DTI accurate and TRACULA able to extract the bvals and
bvecs from the dicom files?
Thanks,
Gabor

You can specify them by setting bvecfile and bvalfile in your
configuration file.

Hi Gabor,
dcm2nii's default setting for VB17 DICOMs should be to rotate the bvecs
that it returns into the voxel/image axes if you have a modern version of
it.
