Convert NIfTI Codes: Convert NIfTI Codes

Description

Codes that appear in the ANALYZE header are mapped to meaningful character strings.

Usage

convert.bitpix(bitpix = NULL)
convert.datatype(datatype.code = NULL)
convert.intent(intent.code = NULL)
convert.form(form.code)
convert.units(units, inverse = FALSE)
convert.slice(slice.code)

Value

A character string.

Arguments

bitpix

is the bit-per-pixel code.

datatype.code

defines data type.

intent.code

is the NIfTI intent code.

form.code

is the $(x,y,z)$ coordinate system.

units

is the units of pixdim[1..4].

inverse

is a logical value that denotes the direction of unit conversion.

slice.code

is the slice timing order.
