Re: [HCP-Users] Seed-based RS functional connectivity for individual subject

Unlike other kinds of cifti files, opening a dconn (even if it is a large file) should not load it into memory, so it should work even on modest computers. Open Location probably will not work on a local file. Please first check that you have the latest version of workbench (currently 1.2.3, chec

Re: [HCP-Users] T1w and T2w sample spacing

Hi Michael, You need to convert DICOM field (0019,1018) into seconds. In your case, it is likely 0.065. I think this means that the DICOM field is in nanoseconds. Peace, Matt. From: mailto:hcp-users-boun...@humanconnectome.org>> on behalf of "Stevens, Michael" mailto:michael.stev...@h

Re: [HCP-Users] T1w and T2w sample spacing

I believe that the DICOM field 0019,1018 (readout sample spacing) for Siemens is units of nanoseconds. A value of 6500 sounds about right if your T1 scan has a BW around 240 Hz/Px. For example, for the young adult HCP data, collected with a BW of 210 Hz/Px, that value is 7400. You just need

Re: [HCP-Users] Seed-based RS functional connectivity for individual subject

Hello Xavier, If you open your dense connectome file using File: Open File, this entails loading ~30 GB of data into memory, which is slow and can indeed make wb_view crash. Instead, it is generally preferable to use File: Open Location, and then enter the file’s URL into Custom: URL. Once th

[HCP-Users] T1w and T2w sample spacing

Hi folks, We're altering some of our HCP scripts to use updated T1w and T2w in a new project and I want to make sure I'm entering the correct "Sample Spacing" values for TOPUP distortion correction in the PreFreeSurferPipelineBatch.sh step. Tim's annotation of the PreFreeSurfer.sh code refers

[HCP-Users] Seed-based RS functional connectivity for individual subject

Dear HCP team, I am trying to calculate resting-state functional connectivity for subject 100307 using a seed in the right cerebral cortex that I have defined using a ROI metric file. I have tried the following -cifti-correlation code: /Applications/workbench/bin_macosx64/wb_command -cifti-corre

It works now, thank you! I had changed the name of the HCP data folder in my desktop. I re-browsed the folder and now it works fine. Thank you very much, Xavier. From: Burgess, Gregory [gburg...@wustl.edu] Sent: Tuesday, January 03, 2017 11:39 AM To: Xavier Guell P

Dear HCP team, I am trying to download individual subject data (100307_3T_tfMRI_MOTOR_analysis and 100307_3T_tfMRI_WM_analysis). The following message appears in the Aspera Connect window: "Error: Destination path directory does not exist (Code: 6)". Is there any solution? Thank you very much,
