Re: [HCP-Users] Gradient nonlinearity correction (gradient coefficient file)

[Harms, Michael]

Hi, Please reply to the list for the benefit of others. Siemen's doesn't allow us to directly distribute the gradient coefficient file.  The release documentation includes a contact at Siemens that you can request the file from.  Be sure he knows that you are requesting the file for the SC72 gradient in the Connectom scanner at WashU.  I'm not sure what this process entails, or if Siemen's requires individuals to sign some sort of agreement first.  Please report back to the list on your experience. That said, why not just use the preprocessed dMRI that HCP already provides, which already includes all the corrections that you listed (gradient nonlinearity, topup, and eddy current correction)? 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: 최용호 <chldydgh0...@gmail.com> Date: Thursday, January 15, 2015 9:14 AM To: "Harms, Michael" <mha...@wustl.edu> Subject: Re: [HCP-Users] Gradient nonlinearity correction (gradient coefficient file) Hi, Michael Harms This is HCP data(HCP Skyra) Becaues HCP data be provided at nifti format, I don't have dicom file.

I run to topup, eddy and then perform gradient nonlinearity distortion correction. but I don't know where Siemens gradient coefficient file is.  Cheers, Ho _______________________________________________ HCP-Users mailing list HCP-Users@humanconnectome.org http://lists.humanconnectome.org/mailman/listinfo/hcp-users   The materials in this message are private and may contain Protected Healthcare Information or other information of a sensitive nature.
