Clarification on CIFTI Files in HCP Aging Dataset

[yasaman shahhoseni]

Dear HCP Data Team,

I hope you’re doing well. I’m working with the HCP Aging dataset and would like to clarify the nature of the CIFTI files available for the fMRI data. Could you confirm whether the CIFTI files contain resting-state fMRI time series data (such as .dtseries files) or if they are Imaging-Derived Phenotypes (IDPs) with one value per voxel or region?

I want to ensure we’re accessing the correct files for our analysis, which requires the full resting-state time series.

Thank you very much for your assistance.

Best regards,
Yasaman

Hi Yasaman,

The Resting State fMRI Preprocessed Recommended package has the timeseries data you need, the CIFTI Multi-modal IDPs Recommended has parcellated IDP brainmaps in CIFTI format. 

Best, 

Jenn
