wrann - write a WFDB annotation file
wrann -r record -a annotator
wrann translates its standard input into an annotation file.
The format of wrann input should be that produced by rdann(1)
. Specifically,
the pipeline
rdann -r record -a iann -f 0 | wrann -r record -a oann
is guaranteed to produce an identical copy of the annotation file read
by rdann, provided that the aux fields of the annotations do not contain
embedded nulls.
The usual application for wrann is as an aid to annotation
file editing: an annotation file may be translated into ASCII format using
rdann, edited using a text editor, and then translated back into annotation
file format using wrann.
It may be necessary to set and export
the shell variable WFDB (see setwfdb(1)
).
