convert_nifti: Convert NIfTI Codes

In oro.nifti: Rigorous - NIfTI+ANALYZE+AFNI Input / Output

Description

Codes that appear in the NIfTI-1 header are mapped to meaningful chartacter strings.

Usage

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

Arguments

datatype.code	defines data type.
bitpix	is the bit-per-pixel code.
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.

Details

switch statements are used to map a numeric code to the appropriate string.

Value

A character string.
