Published Workflows
Objective: Provide an open, modular, extensible platform for single-particle tracking that supports end users and developers across diverse imaging modalities and biological applications.
Why it works: The abstract states that TrackMate combines out-of-the-box usability with modular components that developers can extend for detection, linking, visualization, and analysis, allowing rapid adaptation to specific tracking problems without rebuilding interface and analysis infrastructure.

Objective: Implement a single-particle tracking experiment to study membrane receptor diffusion dynamics and related protein motion.
Why it works: The review frames SPT as a workflow in which labeled molecules are acquired and then analyzed to extract diffusion properties relevant to receptor dynamics.

Stages
- 1.Molecule labelling(library_build)
The abstract identifies molecule labelling as the first implementation stage of SPT.
Selection: Preparation of labeled molecules suitable for single-particle tracking.
- 2.Acquisition(broad_screen)
Acquisition follows labeling so that particle motion can be recorded.
Selection: Collect single-particle tracking data from labeled molecules.
- 3.Data treatment(secondary_characterization)
The abstract explicitly places data treatment after acquisition and before analysis of diffusion properties.
Selection: Process acquired tracking data before diffusion analysis.
- 4.Analysis of protein diffusion properties(functional_characterization)
The review states that SPT implementation culminates in analysis of protein diffusion properties.
Selection: Extract diffusion-related properties from treated single-particle tracking data.
Steps
- 1.Label target molecules for SPT
Generate labeled molecules that can be tracked as single particles.
The abstract presents molecule labelling as the first part of SPT implementation, before acquisition can occur.
- 2.Acquire single-particle tracking data
Record motion of labeled particles for later analysis.
Acquisition follows labeling because particle motion cannot be recorded until molecules are labeled.
- 3.Treat acquired tracking data
Prepare acquired data for interpretation of diffusion properties.
The abstract explicitly orders data treatment after acquisition and before diffusion analysis.
- 4.Analyze protein diffusion properties
Infer diffusion-related behavior of tracked proteins from treated data.
The abstract presents diffusion analysis as the downstream interpretation stage after data treatment.

The abstract supports that it depends on super-resolution microscopy data, but it does not specify acquisition or analysis requirements.; requires super-resolution data appropriate for tracking analyses; The abstract indicates that SPT requires suitable probes, molecule labelling, acquisition, and downstream data treatment and analysis. Specific probe chemistries or hardware are not detailed in the provided text.; requires molecule labelling; requires acquisition workflow; requires data treatment and analysis of diffusion properties; depends on suitable probes and technological improvements
the abstract does not specify temporal resolution, tracking algorithms, or failure modes; The abstract does not claim that SPT alone resolves all mechanistic questions about receptor biology. It also does not specify how the stated constraints and limitations are overcome.; the review states that constraints and limitations exist but the abstract does not specify them
