The SPARC Dataset (SDS) Viewer is a web-based software tool developed by the UCSD FDI lab and MetaCell for SPARC to visualize large NIH SPARC datasets in a graphical viewer. It gives users a visual overview of the folders, files, subjects, samples, and metadata associated with datasets that adhere to the SPARC Dataset structure (SDS) on the SPARC Portal.
It can be launched by clicking the [SDS Viewer] button shown in the image below. You can find this button in any dataset on the Portal! It can also be launched at https://metacell.github.io/sds-viewer/.
