resting-state fMRI time series or functional connectivity matrices from HCP

[Zahra Yazdani]

hello,
I am trying to access resting-state fMRI time series or functional connectivity matrices from HCP.
From the documentation, it seems that I should use the “S1200 Extensively Processed fMRI Data (2017)”, especially “HCP1200 Parcellation + Timeseries + Netmats”.
However, the download link redirects me to BALSA and shows a maintenance notice.( “On Friday May 15, 2026 at 10:30am CDT, BALSA will go offline for several hours to a day for file system maintenance...” )
Could you please clarify where and how I can download the  parcellated time series and connectivity matrices?
Thank you.

[Elam, Jennifer]

Hi Zahra,

BALSA was only down for a few hours on May 15 and has been up since. Register for an account, login, click on the ConnectomeDB tab, then the HCP-YA 2025 project and agree to the Data Use Terms.

The only way to get the “S1200 Extensively Processed fMRI Data (2017, documentation here)” is from the AWS S3 bucket. On the project page, click Get/Reset AWS Credentials to get an AWS key and follow the instructions here under "Connecting to AWS Data Using These Credentials".  

Once you are connected using an S3 browser, open hcp-openaccess>HCP_Resources>GroupAvg then select the HCP_S1200 zip archives or files that you want to download. 

Best,

Jenn
