Hi, You’ll have to be more specific, as there are different “HCP Protocols” that you could be referring to — e.g., what we used for Young Adults on the custom Connectom scanner; what we used for the “Lifespan Piloting” on the custom Connectom scanner; what we used for "Lifespan Piloting" on the Prisma at CMRR.
Please indicate exactly which protocol you are looking at, and where you obtained it. The TR for the dMRI of the Young-Adult HCP on the Connectom scanner was minimized within the context of the MB factor, voxel resolution, and max b-value of those particular scans. Other protocols, with differing MB factor, resolution, and max b-value have also had their TR minimized for that particular scan. If you are looking for a directly importable protocol on a Prisma scanner, see here: http://protocols.humanconnectome.org/CCF/ cheers, -MH -- Michael Harms, Ph.D. ----------------------------------------------------------- Conte Center for the Neuroscience of Mental Disorders Washington University School of Medicine Department of Psychiatry, Box 8134 660 South Euclid Ave. Tel: 314-747-6173 St. Louis, MO 63110 Email: mha...@wustl.edu From: <hcp-users-boun...@humanconnectome.org<mailto:hcp-users-boun...@humanconnectome.org>> on behalf of 韩美贞 <meizhen...@pku.edu.cn<mailto:meizhen...@pku.edu.cn>> Date: Tuesday, March 14, 2017 at 9:08 AM To: hcp-users <hcp-users@humanconnectome.org<mailto:hcp-users@humanconnectome.org>> Subject: [HCP-Users] why didn't choose the minimal TR for DWI sequence? Dear Professors, I have tried the HCP DWI protocol on SIEMENS 3.0T prisma scanner, I noticed the TR can be shorter (than 5520ms) if the other parameters was set same as HCP's. Could you pls tell me why you didn't choose the minimal TR for DWI sequence, which will save a lot of time??? It would be very appreciate to receiving your reply! Thanks!
