ParticleStats

ParticleStats analyzes particle trajectories represented as X,Y coordinates over time to quantify directionality, saltatory runs and pauses, and kymograph-derived dynamics for studying cytoskeletal dynamics, molecular motor function, and chromosome behavior during cell division.

Key Features:

• Input and Output Specifications: Accepts X,Y coordinates of objects over time and outputs analyses, graphical plots, and statistical data.
• ParticleStats:Directionality: Performs global analysis of polarity in cellular processes and quantifies directional movement such as microtubule plus end growth in Drosophila oocytes.
• ParticleStats:Compare: Analyzes saltatory movements characterized by runs and pauses, applicable to processes including chromosome segregation and molecular motor-based transport.
• ParticleStats:Kymographs: Analyzes kymograph images by converting spatial-temporal data into visual formats to study dynamic events such as chromosome separation during mitosis.

Scientific Applications:

• Microtubule plus-end dynamics: Quantitative analysis of microtubule plus end growth patterns in Drosophila oocytes.
• Chromosome segregation: Characterization of saltatory runs and pauses during chromosome segregation.
• Molecular motor-based transport: Comparison of motor-driven particle motility and pause/run behavior.
• Kymograph-based mitotic analysis: Visualization and quantification of chromosome separation dynamics during mitosis.

Methodology:

Transforms raw X,Y coordinate data into analyses, graphical plots, and statistical data; converts spatial-temporal data into kymographs; and integrates graphical representations with statistical analyses.
