extractKinematics.traj {flowcatchR} | R Documentation

## Calculate a set of kinematics parameters from a single trajectory

### Description

The computed set of parameters include `delta.x`, `delta.t` and `delta.v` (displacements and instantaneous velocity), `totalTime`, `totalDistance`, `distStartToEnd`, `curvilinearVelocity`, `straightLineVelocity` and `linearityForwardProgression`, Mean Squared Displacement, velocity autocorrelation, and more

### Usage

    extractKinematics.traj(trajectoryset, trajectoryID,
      acquisitionFrequency = 30, scala = 50)

### Arguments

`trajectoryset` | A `TrajectorySet` object
`trajectoryID` | The ID of a single trajectory
`acquisitionFrequency` | The frame rate of acquisition for the images, in milliseconds
`scala` | The value of micro(?)meters to which each single pixel corresponds

### Value

A `KinematicsFeatures` object
