  • To facilitate the adoption of this format by making existing analysis tools compatible.

Main Methods:

  • Development of a new standardized single-molecule dataset (SMD) file format.
  • Modification of two existing single-molecule data analysis packages to support the SMD format.

Main Results:

  • A new standardized single-molecule dataset (SMD) file format has been proposed.
  • The SMD format is designed for flexibility, accommodating various programming languages, techniques, and analysis strategies.
  • Two established single-molecule analysis packages are now compatible with the SMD format.

Conclusions:

  • Adopting a common data file format is essential for the advancement of single-molecule research.
  • Standardization will enable transparent, reproducible analysis, benefiting both experts and non-specialists.
