Study Palette

BDC Meta-Analysis Study Builder & Query Tool

About

Study Palette is a unified platform for cross-study data discovery and meta-analysis study building within the NHLBI BioData Catalyst ecosystem. It replaces fragmented search interfaces with a semantic, modular platform that enables researchers to discover data, explore variables, build studies, and transition to analysis.
