How to Download Index Files

Access MetaGraph indexes via AWS S3 for local analysis using the MetaGraph command line tool

All indexes are hosted on AWS S3 for public access. Install the AWS CLI following the installation guide (supports Windows, macOS, Linux).

Example commands:

# List available objects in a bucket
aws s3 ls s3://metagraph/refseq/ --no-sign-request

# Download a specific file
aws s3 cp s3://metagraph/refseq/file.dbg . --no-sign-request

# Sync an entire directory
aws s3 sync s3://metagraph/refseq/ ./local-refseq/ --no-sign-request

The --no-sign-request flag indicates public access without AWS credentials.
