Re: [HCP-Users] MELODIC denoising vs. released ICA-FIX datasets

Hi Michael, My initial interest was in comparing aggressive vs. soft regression of the noise ICs. When I tried simply regressing them out using fsl_regfilt with and without the -a flag, though, I realized that my soft denoised file didn't match the HCP denoised file, so this became more of an

Thanks Steve, that's good to keep in mind. Our acquisition is a single "HCP-like" 15 minute run at MB6, 2.1mm isotropic resolution, TR=1s, AP phase encoding, 32-channel head coil on a 3T Skyra; hopefully that gives us a similar temporal profile. Sounds like I should compare our temporal

Making a "nifti version" isn't a simple conversion, as some lengthy conversations on this list have elaborated on. The good news: if you want a single-subject-specific version, that is possible, using -cifti-separate and -label-to-volume-mapping, using the subject's own surfaces. The bad news:

You might want to compare them to the T1 in an example subject (and perhaps also volume surface outline for pial), to see what is really going on. The pial surfaces of the two hemispheres shouldn't overlap outside the medial wall. Are you mapping to the structural volume resolution, or to the

Hi Peter, The data for the new parcellation are available in the BALSA database, see this thread: http://www.mail-archive.com/hcp-users@humanconnectome.org/msg02876.html We recommend using the included Connectome Workbench scene file to conveniently view the data in the wb_view part of the

Glad you got it all figured out. I’m curious though: was this exercise just to understand the various steps internal to FIX (and hcp_fix) or is there some more fundamental reason that you can't use those actual scripts for your processing? cheers, -MH -- Michael Harms, Ph.D.

The lack of a field map is the larger issue, as it makes accurately registering the EPI to the T1w image problematic. Some folks have made use of an "average field map" to attempt to improve upon this situation, but I don't have this code or personal experience with this. Lacking the T2w

Hi Greg, Thank you very much for your detailed response! I have now generated a Movement_Regressors.mat file with the correct 24 parameters (6 rigid body, 6 derivatives, 6 rigid body squared, 6 derivatives squared). As I didn't have code handy to run highpass filtering on the movement
