Codes that appear in the ANALYZE header are mapped to meaningful character strings.
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)| 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. |
A character string.
switch statements are used to map a numeric code to the
appropriate string.
