Choose Your Download Method

Depending on your needs, you can either download the dataset to your own computer or work with it directly in the cloud.

Local Download (AWS CLI)

Best for downloading the data to your personal computer to explore, test scripts, and work offline.

Cloud Access (AWS EC2)

Best for analyzing massive amounts of data directly in the cloud without using up your local storage space.

Method 1

Download from your local machine using AWS CLI

1

Install the AWS CLI

The AWS CLI is required on all operating systems (Windows, macOS, and Linux) to download the dataset. Select your OS below and follow the installation instructions.

Using the official MSI installer is recommended on Windows:

  1. Download the installer from the official download link (AWSCLIV2.msi).
  2. Run the downloaded .msi file and follow the on-screen instructions.

If installing via the command line, use PowerShell (Administrator):

msiexec.exe /i https://awscli.amazonaws.com/AWSCLIV2.msi

Install using the official PKG installer:

curl "https://awscli.amazonaws.com/AWSCLIV2.pkg" -o "AWSCLIV2.pkg"
sudo installer -pkg AWSCLIV2.pkg -target /

Or, if you use Homebrew:

brew install awscli

Download, unzip, and run the installer:

curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
unzip awscliv2.zip
sudo ./aws/install

ARM (aarch64) users should use this URL instead:

curl "https://awscli.amazonaws.com/awscli-exe-linux-aarch64.zip" -o "awscliv2.zip"
unzip awscliv2.zip
sudo ./aws/install

After installation, open your terminal and verify with:

aws --version

For more details, see the official AWS CLI installation guide.

Note

Once the AWS CLI is installed, the following aws commands can be run in essentially the same way across Windows (PowerShell), macOS, and Linux.
Platform-specific differences primarily involve installation methods and file path syntax.

2

List the bucket contents

Use this command to confirm that you can access the dataset:

aws s3 ls s3://braidyn-bc-buckets --no-sign-request
3

Choose what to download

Select the type of data you want to download, then copy the generated command:

Session type
Subject
File type
Download the entire dataset — all subjects, all sessions, all file types. 
aws s3 sync s3://braidyn-bc-buckets ./data/ --no-sign-request

Method 2

Access the data directly from AWS EC2

This option is useful when the dataset is large and you want to analyze it on AWS instead of downloading it to your personal computer.

1

Connect to your EC2 instance

Start an EC2 instance and connect to it using SSH or EC2 Instance Connect.

2

Confirm AWS CLI is available

aws --version
3

List files in the S3 bucket

aws s3 ls s3://braidyn-bc-buckets --no-sign-request
4

Choose what to download

Select the type of data you want to download to EC2, then copy the generated command:

Session type
Subject
File type
Download the entire dataset — all subjects, all sessions, all file types. 
aws s3 sync s3://braidyn-bc-buckets ./data/ --no-sign-request

Notes

Storage

Make sure your local machine or EC2 instance has enough disk space before starting a large download.

AWS costs

Downloading on your own computer does not require EC2, but using an EC2 instance may incur AWS charges.

Stopping downloads

You can stop a running download with Ctrl + C and resume later with the same aws s3 sync command.

EC2 shutdown

If you use EC2, stop the instance after you are done to avoid unnecessary charges.
