EVFishTracking: Detect Fish Tracks

In AustralianAntarcticDivision/EchoviewR: Control of Echoview via COM

Detect Fish Tracks

Description

This function runs fish track detection on an single target echogram Fish track algorithms and settings are explained in the [Echoview Help File]('https://support.echoview.com/WebHelp/Echoview.htm')

Arguments

EVFile	An Echoview file COM object
EVVar	An Echoview single target variable as a character string
FishTrackRegionClass	string indicating the region class name for the fish tracks to be assigned
export	full file path as a text string for an export file (i.e. "C:/FishTracking/Exports/FishTracks.csv"). NULL value skips export of fish tracks.
DataDimensions	numeric Determine which algorithim is used for fish tracks. Accepted values are 2 (single or dual beam) or 4 (split beam)
Alpha.MajorAxis	numeric Increases Alpha gain setting of Major Axis
Alpha.MinorAxis	numeric Increases Alpha gain setting of Minor Axis
Alpha.Range	numeric Increases Alpha gain setting of Range
Beta.MajorAxis	numeric Increases Beta gain setting of Major Axis
Beta.MinorAxis	numeric Increases Beta gain setting of Minor Axis
Beta.Range	numeric Increases Beta gain setting of Range
ExclusionDistance.MajorAxis	numeric Increases distance value of major axis in target gate parameters
ExclusionDistance.MinorAxis	numeric Increases distance value of minor axis in target gate parameters
ExclusionDistance.Range	numeric Increases distance value of range in target gate parameters
MissedPingExpansion.MajorAxis	numeric Increases expansion value of major axis in target gate parameters
MissedPingExpansion.MinorAxis	numeric Increases expansion value ofminor axis in target gate parameters
MissedPingExpansion.Range	numeric Increases expansion value of missed pings range in target gate parameters. 0 disables missed ping expansion
Weights.MajorAxis	numeric 1-100 Assigns the weighting of the major axis
Weights.MinorAxis	numeric 1-100 Assigns the weighting of the minor axis
Weights.Range	numeric 1-100 Assigns the weighting of the range
Weights.TS	numeric 1-100 Assigns the weighting of the target strength
Weights.PingGap	numeric 1-100
MinimumTargets	numeric Minimum number of single targets to be considered a fish track
MinimumPings	numeric Maximum number of pings in a track
MaximumGap	numeric Maximum ping gap between tracks
