compose_transform_to_file: Compose Transforms from ANTsR to a composite file

In muschellij2/extrantsr: Extra Functions to Build on the 'ANTsR' Package

Description

This is a thin wrapper for antsApplyTransforms but is specifically for composing a transform and getting a file out.

Usage

compose_transform_to_file(
  fixed,
  moving,
  transformlist = NULL,
  output_prefix = NULL
)

Arguments

fixed	fixed image defining domain into which the moving image is transformed.
moving	moving image to be mapped to fixed space.
transformlist	haracter vector of transforms generated by antsRegistration where each transform is a filename.
output_prefix	Prefix of output filename to return. The prefix will add comptx.nii.gz to the end

Value

A character filename

Examples

library(ANTsR)
fixed <- antsImageRead( getANTsRData("r16") ,2)
moving <- antsImageRead( getANTsRData("r64") ,2)
fixed <- resampleImage(fixed,c(64,64),1,0)
moving <- resampleImage(moving,c(64,64),1,0)
mytx <- antsRegistration(fixed=fixed , moving=moving ,
                         typeofTransform = c("SyN"), 
                         verbose = TRUE
                          )
composed <- compose_transform_to_file( 
fixed=fixed, moving=moving, transformlist=mytx$fwdtransforms)
