Can I edit annotations with a text editor?

Believe it or not, sometimes users ask this question.

If you have unusual requirements (for example, if you want to change all annotations of a certain type), you may be able to edit annotations more efficiently using a text editor such as emacs. Since annotation files are not text files, however, you will need to convert your files from binary to text form to edit them, and then convert the edited text back to binary form in order to use them further with WAVE . You can do this using rdann and wrann (see rdann(1) and wrann(1), in the WFDB Applications Guide, for details).
