Re: [HCP-Users] unsmoothed ROI to smoothed cifti correlation

2017-05-04 Thread Timothy Coalson
Looks like it does what you wanted. Side note, if you have multiple non-overlapping ROIs to do this with, you could also make them into a dlabel file, then use -cifti-parcellate on the timeseries, and do a -cifti-cross-correlation using it and the smoothed dtseries. However, you'll need to

Use -cifti-merge to make a concatenated dtseries, then you can use -cifti-change-mapping to convert it to dscalar. Tim On Thu, May 4, 2017 at 3:22 PM, Xavier Guell Paradis wrote: > Dear HCP experts, > Is there a way I can create a dscalar.nii file which contains four >

Good to know, thanks - that's consistent with what I'm seeing. Will keep the transformation for now. For future ref to anyone trying this, the corrected sequence is: 1) Extract mean unsmoothed ROI data to text: wb_command -cifti-roi-average ${sub}_${run}.dtseries.nii

[HCP-Users] merge multiple dtseries.nii into one dscalar.nii?

2017-05-04 Thread Xavier Guell Paradis
Dear HCP experts, Is there a way I can create a dscalar.nii file which contains four cope.dtseries.nii files as four different maps? I have been exploring different possibilities with wb_command but can't find the way to do it. Thank you very much, Xavier.

To be clear, depending on the r-value, the Fisher’s z-transform may not change the value much, but that doesn’t mean that the correlation (Pearson’s r) has a *distribution* that is close to Gaussian. cheers, -MH -- Michael Harms, Ph.D.

Ah that makes sense, thanks! The effect of the z transformation is quite subtle (as expected since the correlation distributions are close to gaussian before transformation). From: Harms, Michael [mha...@wustl.edu] Sent: Thursday, May 04, 2017 10:21 AM To: Ely,

I'm trying to download the PTN release of HCP-900 in order to get the netmats, but I'm having trouble locating this data either on AWS (preferred) or on db.humanconnectome.org Can someone direct me to where this release is located? Also, is there a timeline for when a PTN release for HCP-1200

I would probably z transform before averaging across runs, so that you are averaging something with at least an approximately gaussian distribution. cheers, -MH -- Michael Harms, Ph.D. --- Conte Center for the Neuroscience of Mental
