sumann - summarize the contents of a WFDB annotation file


sumann -r record -a annotator [ options ... ]


sumann reads the annotation file specified by record and annotator and produces a tabular summary of its contents, including the number of annotations of each type as well the duration and number of episodes of each rhythm and signal quality.

Options include:

-f time
Begin at the specified time.
Print a usage summary.
-o beat-table rhythm-table
Append summaries of beat and rhythm annotations to the specified beat-table and rhythm-table files. The summaries for the specified record are written as a single line in CSV (comma-separated value) format in each file. If either file does not exist, it is created, and a header line containing column names is written to it. If the -o option is omitted, a more easily readable summary is written to the standard output instead.
Summarize QRS annotations only.
-t time
Stop at the specified time.


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