Write a NIfTI-1 format file

Share:

Description

This function writes an image to NIfTI-1 format, using the standard NIfTI-1 C library.

Usage

1
writeNifti(image, file, template = NULL, datatype = "auto")

Arguments

image

An image, in any acceptable form (see retrieveNifti).

file

A character string containing a file name.

template

An optional template object to derive NIfTI-1 properties from. Passed to updateNifti if image is an array.

datatype

The NIfTI datatype to use when writing the data out. The default, "auto" uses the R type or, for internal images, the original datatype. Other possibilities are "float", "int16", etc., which may be preferred to reduce file size. However, no checks are done to ensure that the coercion maintains precision.
