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

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

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 input, too.
Hope this helps,
a.y

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 need
to use dcm2nii with correction for slice angulation
