Description
flowio is an agent skill for reading, inspecting and writing Flow Cytometry Standard files with FlowIO. It handles FCS 2.0, 3.0 and 3.1 files. FlowIO is a lightweight, low-level reader and writer, and it is the right choice for reading FCS files, inspecting the HEADER, TEXT and ANALYSIS segments and channel metadata, retrieving event data as a two-dimensional NumPy array, and reading legacy files that contain several datasets. It can also write list-mode, single-precision FCS 3.1 files, and prepare data for pandas, machine learning or downstream cytometry tools. The skill targets FlowIO 1.4.0, the current stable release verified on 30 September 2026. Its standalone checks used Python 3.13, NumPy 2.5.3 and pandas 3.0.6. Use it when you have cytometry files to read or write, or when you need the raw metadata of a file rather than a higher-level analysis. It is part of the k-dense-ai scientific agent skills repository on GitHub, which has about 49,600 stars. The listing shows it as free, and it has about 1,800 installs. Its security audits show passes from Gen Agent Trust Hub, Socket and Snyk.…
