wrann - write a DB 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.

The shell variable DB should be set and exported (see setdb(1) ).
