Re: [HCP-Users] Follow-up to: Obtaining the MNI coordinates of cluster peaks in the melodic_IC.dscalar.nii ICA maps

Thanks for the reply Matt. I didn't quite understand what you mean by: " I would do your mapping in individual subjects." In case it was not clear, the tractography is of course performed in individual subject space using the MSMAll surfaces in the subject directory of the T1w folders. My

Re: [HCP-Users] Offline vs. online gradient nonlinearity correction

1. Yes 2. We use dcm2nii. 3. Probably I would use offline so you are sure that all of your images are being corrected the same way and have control over how the resampling is being done (i.e. not adding blurring from trilinear interpolation). Peace, Matt. From:

FYI: We are switching over to using ‘dcm2niix’, which is Chris Rorden’s newer, actively maintained conversion tool. -- Michael Harms, Ph.D. --- Conte Center for the Neuroscience of Mental Disorders Washington University School of Medicine

[HCP-Users] HCP dMRI quality control question

Hi HCP Consortium, The dMRI protocol has 270 directions (excluding b0), but there are several subjects with dMRI data less than 270 directions (shown by the bval file). For example, subject 578158 only has 164 DWI (b0 excluded). Is this a known quality control issue? Best regards, Frank

I meant the volume to surface mapping, so it sounds like your plan should work fine. Peace, Matt. From: Claude Bajada > Date: Friday, August 4, 2017 at 5:17 AM To: Matt Glasser >, Timothy

That means they didn¹t complete all of the scans. It is up to you whether you want to include such subjects in your study. Peace, Matt. On 8/3/17, 10:00 PM, "hcp-users-boun...@humanconnectome.org on behalf of Fang-Cheng Yeh"
