Area of Science:

  • Biophysics
  • Data Science

Background:

  • Single-molecule fluorescence experiments generate complex data.
  • Existing data formats can hinder data exchange and long-term accessibility.

Purpose of the Study:

  • Introduce Photon-HDF5, an open and efficient file format.
  • Facilitate simplified data exchange and long-term accessibility for photon-counting detector data.

Main Methods:

  • Photon-HDF5 is based on the Hierarchical Data Format version 5 (HDF5).
  • It supports raw photon data (timestamp, channel number) and comprehensive metadata.
  • A reference Python library (phconvert) is provided for file creation and conversion.

Main Results:

  • Photon-HDF5 enables storage of raw photon data, setup/sample descriptions, provenance, and custom data.
  • Specifications are publicly hosted and open for community contributions.
  • Code examples and a Python library are available for broad adoption.

Conclusions:

  • Photon-HDF5 offers a standardized, flexible, and accessible solution for single-molecule fluorescence data.
  • The open-source nature and community-driven development encourage widespread adoption.
  • This format will enhance reproducibility and collaboration in biophysics research.
