datatype: Change Data type for img

Description

Tries to figure out the correct datatype for image. Useful for image masks - makes them binary if

Usage

datatyper(
  img,
  type_string = NULL,
  datatype = NULL,
  bitpix = NULL,
  trybyte = TRUE,
  warn = TRUE
)

Value

object of type nifti

Arguments

img

nifti object (or character of filename)

type_string

(NULL) character of datatype and bitpix. Supercedes both datatype and bitpix. If specified convert.datatype[[type_string]] and convert.bitpix[[type_string]] will be used.

datatype

(NULL) character of datatype see convert.datatype

bitpix

(NULL) character of bitpix see convert.bitpix

trybyte

(logical) Should you try to make a byte (UINT8) if image in c(0, 1)?

warn

Should a warning be issued if defaulting to FLOAT32?

Examples

img = nifti(array(rnorm(10^3, sd = 1000), dim = rep(10, 3)))
rimg = round(img)
newnii(datatyper(rimg))
rimg = datatyper(rimg, type_string= "FLOAT32")
