Data

The Data section prepares everything downstream analysis needs.

Datasets

Upload or convert data files:

FormatNotes
.h5adPreferred; validated at ingest
CSV/TSV count matrixConvert to AnnData via Convert
10x HDF5 (.h5)Convert to AnnData
10x MTX zip bundleConvert to AnnData

After upload, the dataset row shows cell/spot counts, gene count, and ingestion status. Failed ingestions display an error message you can use to fix the file.

Metadata

Define a metadata table keyed to barcodes or sample IDs in the dataset. Columns typically include sample, condition, donor, and batch. Before each analysis run the platform validates that join keys match and merges columns into AnnData obs.

Use Validate against dataset to catch mismatched IDs before running expensive jobs.

Design

Specify which obs columns define biological groups and which column identifies biological replicates. The design table feeds contrast definitions and future bulk statistical models.

Contrasts

Save named comparisons (for example Treatment vs Control on the condition column). Contrasts appear in the Analyze DE step when comparison mode is condition or sample.

Ingestion

The Ingestion panel summarizes format detection, conversion jobs, and any sidecar files used during CSV/10x import.

Tips

  • Run metadata validation after every metadata edit; stale flags appear on Runs if you change metadata after DE.
  • Spatial datasets must include obsm['spatial'] coordinates in the .h5ad.
  • Biomarker workflows need a label column with at least two classes (default: condition in obs).
