Cells2Stats workflow

The Cells2Stats nextflow workflow that generates multiomic data.

The cells2stats-nf workflow by Element Biosciences is a Nextflow workflow that generates multiomic data from cell screening run data produced by AVITI24™ Systems.

This workflow runs as part of ElemBio Cloud, but can also be used independently and reproducibly in any Nextflow environment (local or cloud-based).

Workflow summary

Description

Converting raw images is the necessary first step to view multiomic data in CytoCanvas. This single step pipeline uses the Cells2Stats Software to process multiomic data.

Workflow diagram

Release notes

The workflow repository is maintained on GitHub, where you can find tags, release notes, and the latest updates.

Inputs

Input	Description	Constraints
Run Directory	An AVITI24 System cell screening run directory.	Required
Cell Screening Run Manifest	By default, the run manifest in the output run directory is used. If required, an alternate run manifest can be provided to overwrite cells and pass metadata.	Optional
Cell Segmentation	If required, an alternate cell segmentation file set instead of the segmentation provided in the run directory.	Optional
Parameters	In addition to the dataset, parameters can tune the output.	Optional

Output

Cells2Stats outputs cell screening metrics and visualization data for CytoCanvas™. Depending on the parameters used, the output directory may be different. See Cells2Stats outputs for specific details of output files.
