Restricted datasets

Some datasets in the repository cannot be downloaded without authorization, because the upstream source unfortunately does not permit open distribution. They are marked “Restricted access” on their page, and downloading their files fails with a 401 Unauthorized error. Access can be granted with an authorization token:

If you need access to these datasets, fill in the form below. You will receive an email with a link to verify your address. Each request is then reviewed before it is approved, based on the information you provide; once approved, the token is sent to you by email.

How do you intend to use the data?
Send it with each download

Pass the token in the WWW-Authenticate HTTP request header, replacing <TOKEN> with the actual token string:
```
WWW-Authenticate: <TOKEN>
```
For example, with curl:
```
curl --header "WWW-Authenticate: <TOKEN>" \
     https://networks.skewed.de/net/add_health/files/comm26.gt.zst > comm26.gt.zst

Or let graph-tool send it

If you access the repository via graph-tool, store the token in a file named .gt_token in your home directory:
```

```
