Re: [HCP-Users] Hcp Data with non-overlapping parcellations

If you are interested in using matlab, another possibility to consider is that the 'ciftiopen' matlab tool can load .dlabel.nii and .pconn.nii files (and thus I assume .dconn.nii files as well).  That will just give you the data values stored in each file type, but the indices in

[HCP-Users] MRI parameters

Hello, I am using MRI parameters for the structural T1w and T2w scans from the Glasser and Van Essen 2011 paper. Are these parameters, particularly the TE and TR, fixed or do they/are they expected to vary between participants and scans? Thank you in advance for your help. Kind regards, Rachel

Re: [HCP-Users] MRI parameters

The particular choice of TR/TE may vary between studies, but for a given study they are typically fixed for all the participants. cheers, -MH --  Michael Harms, Ph.D. --- Conte Center for the Neuroscience of Mental Disorders

[HCP-Users] Question regarding Topup warp field output

Hello again, I have a question about the warp fields that are produced by topup. Can you please tell me how they relate to regular field maps, especially in terms of the difference in volumes (3 vs. 1)? In addition, has there been any testing done to see how the two types of distortion

Sorry, the -*-label-export-table commands don't put the unlabeled key in the text file. Use -file-information on them instead to check what key value the "???" label is (it means the unlabled value). Tim On Wed, Nov 18, 2015 at 12:54 PM, Timothy Coalson wrote: > Inline
