Re: [HCP-Users] HARDI gradient direction file

[Harms, Michael]

Hi, Which specific gradient direction file are you referring to?  There is the 3 shell set that we used for HCP on the WU Connectome scanner;  there is the 2 shell set that we used for Lifespan Phase 1b piloting on the WU Connectome scanner; and there is the 2 shell set that was used for Lifespan Phase 1b piloting on the CMRR Prisma. The bigger issue is that you’re going to have to change a number of acquisition related parameters since the Trio gradients don’t support HCP/Lifespan-style DWI acquisitions. 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> on behalf of Joy Williams <w...@yorku.ca> Date: Friday, March 11, 2016 at 8:31 AM To: "hcp-users@humanconnectome.org" <hcp-users@humanconnectome.org> Subject: [HCP-Users] HARDI gradient direction file Hello, We would like to acquire HARDI DTI data at our MRI Facility.  We have a Siemens Tim Trio (running Syngo VB17) and have the ability to run the DTI sequence using a user specified gradient file.  Could you possibly send me the gradient directions that you use for your HARDI sequence? (approximately 60 directions?)
