Examples

fi <- antsImageRead(getANTsRData("r16"))
mi <- antsImageRead(getANTsRData("r27"))
reg <- antsRegistration(fi, mi, "TV[2]")
#> TV[2] is not deterministic/reproducible. Use setANTsDeterministic(TRUE) to remedy.
velocityField <- antsImageRead(reg$velocityfield)
field <- integrateVelocityField(velocityField, 0.0, 1.0, 10)
