makePointsImage: Create label image from physical space points

In stnava/ANTsR: ANTs in R: Quantification Tools for Biomedical Images

Create label image from physical space points

Description

Creates spherical points in the coordinate space of the target image based on the n-dimensional matrix of points that the user supplies. The image defines the dimensionality of the data so if the input image is 3D then the input points should be 2D or 3D.

Usage

makePointsImage(pts, mask, radius = 5)

Arguments

pts	input powers points
mask	antsImage mask defining target space
radius	for the points

Value

antsImage is output

## Not run: 
mni <- antsImageRead(getANTsRData("mni")) %>% getMask()

powersLabels <- makePointsImage(powers_areal_mni_itk[, 1:3], mni, radius = 3)

## End(Not run)
