DiRatio: Directionality Table

In ocbe-uio/CellMigRation: Track Cells, Analyze Cell Trajectories and Compute Migration Statistics

Description

Directionality Ratio is the displacement divided by the total length of the total path distance, where displacement is the straight line length between the start point and the endpoint of the migration trajectory,

Usage

DiRatio(object, TimeInterval = 10, export = FALSE, ExpName = NULL)

Arguments

object	CellMig class object, which is a list of data frames resulted from the PreProcessing.
TimeInterval	A numeric value of the time elapsed between successive frames in the time-lapse stack.
export	if 'TRUE' (default), exports function output to CSV file
ExpName	string

Details

Directionality Ratio and Directional persistence

Value

An CellMig class object with a data frame stored in the DRtable slot. It contains nine rows: "Cell Number", "Directionality Ratio","Mean Cumulative Directionality Ratio", "Stable Directionality Ratio", "Number of returns","Min CumDR", "Location of Min CumDR, Steps with less CumDR than DR", "Directional Persistence"
