Name

rdedfann - extract annotations from an EDF+ file

Synopsis

rdedfann -r edffile [ options ... ]

Description

This program prints the annotations from an EDF+ file in the same format as rdann does for WFDB-compatible annotation files.

Options include:

-h
Print a brief usage summary. -v Verbose mode (print column headings).

Note that the annotation mnemonics in EDF+ files do not in general match those used in WFDB-compatible annotation files, so that it will usually be necessary to translate those that come from EDF+ file before the text can be converted by wrann. For example, this command can be used to extract annotations from foo.edf, change the EDF+ annotation type "QRS" to the WFDB type "N", and then produce a WFDB-compatible annotation file foo.edf.qrs:
rdedfann -r foo.edf | sed "s/QRS/ N" | wrann -r foo.edf -a qrs

Environment

It may be necessary to set and export the shell variable WFDB (see setwfdb(1) ).

Availability

This program is provided in the convert directory of the WFDB Software Package. Run make in that directory to compile and install it if it has not been installed already.
