AWS S3 "hcp-openaccess/HCP"

[Matthieu Vanhoutte]

Hello HCP's experts,

I am trying to get specific preprocessed volume HCPYA 2025 release via AWS S3 bucket, but I am confused why there are only 500 subjects within the "hcp-openaccess/HCP" folder and not the 1113 subjects from the initial s1200 release?

Since, "due to these updates, data from this 2025 Release should not be mixed with the previous "S1200" Release (from 2017)", how could I catch all new updated preprocessed files from 2025 release?

Best,

Matthieu

  Hey, I ran into the same thing. The 2025 release isn’t on S3 — only on the BALSA portal, and you need the IBM Aspera client (through the web UI) to download it. They said moving it to S3 is planned but low priority right now.

hcp-openaccess/HCP_1200 exists on s3, but it is the older S1200 release (matching what was on connectomeDB, I believe), not the new 2025 version that is on balsa.

It seems that hcp-openaccess/HCP (2025 release) exists on s3 but only for 500 subjects. What do these 500 subjects correspond to?

Hi Mattheu,

hcp-openaccess/HCP is data from the 500 Subjects release (2014). Go to hcp-openaccess/HCP_1200 for data from the S1200 Release (2017, all released subjects). Data from the 2025 update release are only available on BALSA (ConnectomeDB tab) through download via Aspera (requires Aspera Connect plug in). We are planning to offer a non-Aspera way to get the data in packages and a REST interface for getting individual files, but it will likely take a few months to get those in place.

 

Best,

Jenn

I have a related question, in order to get my AWS credentials for the S3 data, I have to log-in to connectome db, so how I will be able to do so after you shut the connectome db down??

Best, 

Ali.

Hi Aly,

We are planning to add the AWS keys functionality to BALSA soon, but not immediately. Please get and save your S3 key ID and secret key from ConnectomeDB to use until we have this functionality in place in BALSA. I find once I have the keys set in my S3 browser I rarely have to regenerate them. You also might transfer the S1200 data you need for your current work locally before ConnectomeDB shuts down next week.

 

Best,

Jenn
