write.amiramesh: Write a 3D data object to an amiramesh format file

In nat: NeuroAnatomy Toolbox for Analysis of 3D Image Data

Write a 3D data object to an amiramesh format file

Description

Write a 3D data object to an amiramesh format file

Usage

write.amiramesh(
  x,
  file,
  enc = c("binary", "raw", "text", "hxzip"),
  dtype = c("float", "byte", "short", "ushort", "int", "double"),
  endian = .Platform$endian,
  WriteNrrdHeader = FALSE
)

Arguments

x	The image data to write (an im3d, or capable of being interpreted as such)
file	Character vector describing a single file
enc	Encoding of the data. NB "raw" and "binary" are synonyms.
dtype	Data type to write to disk
endian	Endianness of data block. Defaults to current value of .Platform$endian.
WriteNrrdHeader	Whether to write a separate detached nrrd header next to the amiramesh file allowing it to be opened by a NRRD reader. See details.

Details

Note that only 'raw' or 'text' format data can accommodate a detached NRRD format header since Amira's HxZip format is subtly different from NRRD's gzip encoding. There is a full description of the deteached NRRD format in the help for write.nrrd.

Examples

d=array(rnorm(1000), c(10, 10, 10))
tf=tempfile(fileext='.am')
write.amiramesh(im3d(d, voxdims=c(0.5,0.5,1)), file=tf, WriteNrrdHeader=TRUE)
d2=read.nrrd(paste(tf, sep='', '.nhdr'))
all.equal(d, d2, tol=1e-6)
