        Hi Bhushan,

        Thank you so much for your reply. So <prefix_filename>.dwi.RAS.bvec and <prefix_filename>.dwi.RAS.correct.nii.gz are my new bvec rotated and dti with epi distprtion corrected? Thanks.

        Best regard,
        Kim

            Yes, <prefix_filename>.dwi.RAS.correct.nii.gz is distortion corrected diffusion-weighted images and <prefix_filename>.dwi.RAS.bvec is corresponding bvec file.

            Hello , I am wondering whether “bdp” tool in BtrainSuite can correct for motion artifact in diffusion data or not !

              Hi, currently we do not support motion correction. One way you can correct for motion is by rigid registration of all diffusion weighted images with one reference image (like a b=0 image). You can use our affine registration addon tool to achieve this – https://neuroimage.usc.edu/neuro/Resources/BDPAddons#affineReg

                T1w image is the first argument to BDP on command line. See below for usage. This file should be the bias-field corrected output from BrainSuite in nifti-1 format.

                bdp.sh <BFC FILE> [OPTIONAL FLAGS] --nii <NIFTI FILE> --bvec <GRADIENT FILE> --bval <B-VALUE>

                More usage details can be found here: http://brainsuite.org/processing/diffusion/pipeline/
