Single Cell on Polly

Polly delivers the highest quality single cell data to fit diverse analysis methods & pipelines. All datasets are Polly Verified, i.e. harmonized with a configurable, granular & transparent curation process.


How Does Single Cell Data on Polly Become ML-ready?

Why Access Single Cell Data on Polly?

Configure Curation to Fit Your Analysis Needs

Request extra metadata fields, use custom ontologies, or annotate cell types with your preferred marker database.

Process, annotate, and QC single cell data using a scientifically validated Polly pipeline or parameters provided by the author in the original publication.

Use Data You Can Trust

All single cell datasets delivered by Polly undergo ~50 QA checks to ensure quality and provenance.

Assess the intrinsic quality of the data (genes, cells, measurements) with comprehensive QA reports detailing the processing methodology.

Work With Data in Flexible Ways

Avail unrestricted data connectivity and consumption between Polly and your preferred analysis environments. Use APIs to stream harmonized data on Polly to external tools and applications.

Polly Verified – Our Quality Guarantee

We use at least ~50 QA Checks to ensure every dataset is:


Data validation checks ensure that all cell & dataset level metadata annotations contain non-NULL and non-blank values.


Rigorous QC checks to ensure metadata attributes are human readable and  accurately assigned at all levels (dataset, cell).


Normalization & Batch Effect correction applied wherever necessary to eliminate technical variations and enable meaningful comparisons between cells.


Doublets, which can arise during sample preparation and confound analysis, are identified and removed.


Poor quality cells and genes are filtered out. Genes that drive biological variation are retained and used for downstream analyses.
