NODES aims to develop a community-driven standardized data format for psychoneuroendocrinology (PNE). It aims to simplify data sharing and reuse by providing guidelines and tools for organizing and validating datasets before publication. Sharing hormonal data in PNE is challenging due to its complexity and the lack of common standards, which limits openness and reproducibility. NODES addresses these issues by defining the essential information needed to interpret PNE data accurately, focusing on accessibility and compatibility to promote collaboration and improve research transparency across the field.
