If your internet connection is slow or unreliable we recommend downloading the data directly from Amazon Web Services S3 storage using AWS CLI tool (https://docs.aws.amazon.com/cli/latest/index.html)
aws s3 sync --no-sign-request s3://openneuro.org/<dataset_accession_number> <target_folder>
Where <dataset_accession_number> is the id of the dataset (for example ds000030) and <target_folder> is a local path where data will be transferred to.
You can use --include and --exclude flags to download only a subset of the dataset (see https://docs.aws.amazon.com/cli/latest/reference/s3/index.html#use-of-exclude-and-include-filters ).
This method will allow you to download the most recent dataset snapshot. Accessing historical snapshots via S3 is currently not supported.
