Dear FSL's users,
I have three DWI acquisitions for each subject included in my study (d500,d750,d1000). In each of the acquisition I have 1 reference image (b=0) and 25 DWI. In order to increase the quality I create a 4D image where I have concatenated the three images (from three different acquisitions) with 75 DWI and 3 reference images. I am not sure if this method is scientifically correct but how is possible to concatenate also the bvecs and bvals in order to create an extended sequence from the bvals and bvecs of the original images (d500,d750,d1000)?
Thank you very much,
Giuseppe
