analyze.read.char.field: Read a fixed length character field of an ANALYZE 7.5 header.
In freesurferformats: Read and Write 'FreeSurfer' Neuroimaging File Formats
analyze.read.char.field R Documentation
Read a fixed length character field of an ANALYZE 7.5 header.
Description
Read a fixed length character field of an ANALYZE 7.5 header.
Usage
analyze.read.char.field(filehandle, n)
Arguments
filehandle
connection to read from.
n
integer, the number of bytes of the field.
Value
character string, the field content with the trailing zero bytes removed. The bytes are interpreted as
ISO-8859-1 (latin-1) and converted to UTF-8, which cannot fail: the ANALYZE 7.5 fields originator,
generated, patient_id and friends contain whatever the software that wrote the file put there, including
bytes that are not valid UTF-8 (the SPM software, for example, stores an image origin as 3 little endian
integers in the originator field). Decoding them as UTF-8 would fail or return NA for a subset of the
possible byte values.
