License acceptance

Two licenses apply:

  • The dataset license (CC0 1.0) covers the brain and participant data.

  • The stimulus license (closed, research-only) covers the stimulus images.

On the very first download the licenses are presented as Type "I AGREE" prompts. The acceptances persist across sessions, so the prompts only appear the first time you run download(...) against a new data directory.

Reviewing up front

If you’d rather review and accept the licenses before any download(...) call, use the standalone helper:

from laion_fmri.download import accept_licenses

accept_licenses(include_stimuli=True)

  • Without include_stimuli, only the dataset license is prompted.

  • With include_stimuli=True, both licenses are prompted in sequence.

Errors

  • A declined dataset license raises LicenseNotAcceptedError.

  • A declined stimulus license raises RuntimeError.

Both are the same exceptions download(...) raises internally, so subsequent download calls behave identically whether acceptance happened standalone or inside a download.
