Re: [HCP-Users] ROI parcellation

[Harms, Michael]

Also, we encourage you to work in CIFTI-land so as to have a surface-based analysis of the cortical data.  But to answer your question, volumetric versions of both those FS parcellations are available in each subject's MNINonLinear folder; e.g.,  100307/MNINonLinear/aparc+aseg.nii.gz 100307/MNINonLinear/aparc.a2009s+aseg.nii.gz Those particular files should be part of the standard Structural package. 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 On 12/15/15 11:51 AM, "Greg Burgess" <gcburg...@gmail.com> wrote: Hi Joelle, You should be aware of potential issues with using anatomically-defined ROIs for rfMRI network analysis.

So currently, the 2 available parcellation schemes are the Freesurfer Desikan-Killiany (aparc+aseg.mgz) and Destrieux (aparc.a2009s+aseg.mgz) in the structural extended preprocessed/T1w/mri folder? Im presuming these are in the subject's T1 individual subject space. Are you aware whether these parcellation schemes are already available in the MNI standard space? The goal is to parcellate the functional BOLD data (which are currently in MNI standard space; Ie in the FIX extended package, the MNINonLinear/Results/rfMRI_REST1_LR/rfMRI_REST1_LR_hp2000_clean.nii). Or alternatively, if you could point me to where the volumetric functional BOLD data in T1 space is (I cannot locate it in the FIX extended package - this only seems to have func already normalized to MNI), I could directly apply the aparc+aseg parcellation (that's in T1 space) to this.

If you are interested in a functional parcellation, there is the Gordon et al. parcellation derived from non-HCP rfMRI data.  A parcellation that incorporates the myelin maps and rfMRI data and which is specifically derived from a subset of HCP participants is in the works (from Matt G.) 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: Joelle Zimmermann <joelle.t.zimmerm...@gmail.com> Date: Tuesday, December 15, 2015 9:35 AM To: "hcp-users@humanconnectome.org" <hcp-users@humanconnectome.org> Subject: [HCP-Users] ROI parcellation Hi everyone, Does HCP have a specific ROI parcellation that is commonly used/recommended? I  would prefer to begin with anatomically (rather than functionally defined) ROIs. My goal is to parcellate the voxel-wise time series into larger ROIs. I've previously used the Desikan-Killiany atlas, but ideally would be interested in using something with a finer parcellation. The only HCP parcellation I was able to find was the parcellation from the ICA decomposition (resulting in one timeseries per ICA component), with 25, 50, 100, 200, 300 components. However, I don't think this is something I am interested in, as a single node (ie component) may comprise voxels that are scattered across the brain. Is there anything like an anatomical ROI parcellation that's typically used by HCP people?
