hi folks, maybe a common Q. but could not find an answer in the archive
data sets i want to bedpost, i have 2 diffusion acquisitions for each subject, same day
same acquisition parameters, directions etc.
1. suggested by someone i should concatenate the 2
i.e. put at the b=0 at the beginning, then conncatenate all the diffusion weighted
volumes and also the bvec files, and then feed this into the stream,eddy cor. rot bvec
2. actually averaging seems small errors from registration would nagate any increase in snr
3. only use 1 acquisition from each subject
whats your advice ?
