getZeroKoord: Find points of origins

In mknoll/imageanalysisBrain: Analysis of Brain Imaging Data

Description

Determines the point of origin for a given volume by first selecting the

Usage

getZeroKoord(data, sparse = 500, draw = FALSE, col = "yellow",
  drawsteps = 15)

Arguments

data	data frame of volume for which the center or origin should be calculated
sparse	select only each n. voxel (n=sparse) to speed up calculations
draw	draw the identified planes
col	color of planes
drawsteps	select only each n. voxel (n=drawsteps) to draw as identified plane

Value

coordinates belonging to the point of origin (Zero Coordinate)

Examples

data <- data.frame(x=rep(1:10, 5), 
y=c(rep(1,10),rep(2,10),rep(3,10),rep(4,10),rep(5, 10)), 
z=rep(1, 50), rnorm(50))
data$COORD <- encodeXYZToCOORD(data$x, data$y, data$z)
getZeroKoord(data, 1)
