FlowIO: Flow Cytometry Standard File Handler

Overview

FlowIO is a lightweight Python library for reading and writing Flow Cytometry Standard (FCS) files. Parse FCS metadata, extract event data, and create new FCS files with minimal dependencies. The library supports FCS versions 2.0, 3.0, and 3.1, making it ideal for backend services, data pipelines, and basic cytometry file operations.

When to Use This Skill

This skill should be used when:

FCS files requiring parsing or metadata extraction

Flow cytometry data needing conversion to NumPy arrays

Event data requiring export to FCS format

Multi-dataset FCS files needing separation

Channel information extraction (scatter, fluorescence, time)

Cytometry file validation or inspection

Pre-processing workflows before advanced analysis
