[HCP-Users] Creating Custom dlabel File

HCP users, I would like to create a custom dlabel file with particular ROIs from the Glasser 360 surface atlas. Here is what I have done so far: 1) First I separated individual ROIs into their dscalar files with wb_command -cifti-label-to-roi 2) I can easily visualize all dscalar files within

Re: [HCP-Users] Slice-timing correction and latency structure of resting-state fMRI data

Technically, what should matter more is what frequencies dominate the correlation in the data of interest - if they are lower enough in frequency than your sample rate (and therefore slice timing spread), then each latency should produce reasonable maps. However, this also means that when you

Re: [HCP-Users] Creating Custom dlabel File

Creating a label file from ROIs is a bit more complicated than a single command (label files automatically have a guarantee that the areas don't overlap, but arbitrary ROIs can overlap). >From what you currently have, one way to get to a new dlabel file is to concatenate the ROIs you want to use

Re: [HCP-Users] Maximum values for cognitive scores

Hi Ariana, I did find these maximum values for the ASR raw scoring: * ASR internalizing (maximum score for raw scores) = 78 * ASR externalizing (maximum score for raw scores) =70 * ASR anxiety and depression (maximum score for raw scores) = 36 * DSM depression (maximum score for

Re: [HCP-Users] clustering of subcortical structures - flipping and smoothing

Dear all, Thanks for these very helpful replies. We can see that smoothing across boundaries will create strange effects at the edges (we had overlooked the 2mm parcel-constrained smoothing). Thanks for pointing that out. I am unsure from the below replies if there is a way to avoid having

[HCP-Users] Slice-timing correction and latency structure of resting-state fMRI data

Dear all, I am analyzing the latency structure of some of the HCP resting-state fMRI data and I want to make sure that this makes sense, given that no slice-timing correction has been applied to the data. I would appreciate it if someone could confirm that the following reasoning is correct:

Re: [HCP-Users] Slice-timing correction and latency structure of resting-state fMRI data

The TR=0.72s, but I think that is correct. Peace, Matt. From: > on behalf of "HINDRIKS, RIKKERT" > Date: Tuesday, September 5, 2017 at 8:48 AM To:
