Use to settle PNAS Nexus's open-access decisions — confirm the gold-OA model and the article processing charge (APC), check eligibility for waivers/discounts (low-/middle-income countries, Read & Publish, membership) and funder compliance, and choose the license (CC BY vs CC BY-NC). This is PNAS Nexus's signature pre-submission decision; it replaces flagship PNAS's Direct/Contributed track choice (PNAS Nexus has no such track).
