ROSMAP-Compass

Aging, Alzheimer’s Disease (AD), and neurodegeneration are among the most pressing challenges in healthcare. Thanks to rapid advances in single-cell genomics, researchers now have powerful tools to dissect complex tissues at unprecedented resolution, revealing key molecular and cellular processes that drive disease. Large-scale datasets, such as those generated by the Religious Order Study and Rush Memory and Aging Project (ROSMAP), provide an invaluable resource for understanding the biology of aging and neurodegeneration.

Here, we present ROSMAP-Compass—a user-friendly webserver empowering investigators to explore 7.5 million sequenced single cells with over one billion precomputed gene-level tests. By leveraging the state-of-the-art T2T genome reference for realignment and implementing rigorous measures to eliminate data leakage and duplicated cells, ROSMAP-Compass ensures high-quality data integration. This unified platform facilitates deeper insights into AD pathogenesis and aging by making cutting-edge single-cell analyses more accessible to the broader research community.

FAQ
