convert_nifti: Convert NIfTI Codes

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

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)

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.

Details

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

Value

A character string.
