About the resource
Multiome Atlas organizes publicly collected multiome libraries into a consistent browsing layer while preserving the boundaries, provenance and evidence level of every independent analysis.
Data model
Each library retains its existing independently fitted embeddings. The portal supports comparison of metadata and evidence across libraries, but does not imply that UMAP positions are directly comparable between entries.
Pairing
RNA and ATAC observations are joined through validated cell identities. The same retained-cell selection is applied to both modalities and all three visualization spaces.
Provenance
Every library keeps its species, study, dataset, reference, source URL and original row index so exported cells can be traced back to the registered source data.
Reuse
Fast Parquet and JSON assets support the portal. Registered H5MU files remain the source for complete RNA and ATAC matrices.
Annotation policy
RNA cluster markers support the displayed identities. ATAC and WNN plots inherit those labels through exact pairing; they are not independent ATAC cell-type predictions.
Multiple marker families and differential or abundance support.
Evidence supports a lineage or broad class rather than a narrow identity.
Provenance label for cell lines or other explicit source identities.
A candidate is retained as a hypothesis and remains visibly qualified.
Evidence is insufficient for a supported biological identity.
