Dear HCP developers and users, >From what I understood for the HCP DTI dataset this is true: “Sampling in q-space includes 3 shells at b = 1000, 2000 and 3000 s/mm2. For each shell, 192 data points are obtained, corresponding to 90 diffusion gradient directions and 6 b = 0's acquired twice, with the phase encoding direction reversed for each pair (i.e. LR and RL pairs) “
Please correct me if I’m wrong. According to above, in total we should 6 datasets all has 96 (90+6) volumes but different PE direction and b-values. Would you please explain to me what does the HCP raw data naming convention means here? i.e. I don’t know why we should have 95, 96 ,and 97 directions? I do appreciate your elaboration. Thank you, Mahmoud _______________________________________________ HCP-Users mailing list [email protected] http://lists.humanconnectome.org/mailman/listinfo/hcp-users
