Introduction

This command allows getting markers as a struct array.

Marker struct description

Marker.label;     % label of marker
Marker.position;  % position in seconds.
Marker.duration;  % duration in seconds.
Marker.value;     % value associated with marker
Marker.targets;   % cell array of strings. Labels of targeted channels. Empty if the marker is GLOBAL.

Default usage

function main(varargin)
anywave('init', varargin);
markers = anywave('get_markers');

This code will get ALL the markers loaded with the current data file.

Add an extra parameter to the function

In order to specify constraints or requirements on the data we want to access to, the function allows an extra parameter which must be a struct.

Get markers by their labels

function main(varargin)
anywave('init', varargin);
cfg = [];
cfg.labels = {'seizure', 'EI' };
markers = anywave('get_markers', cfg);
if ~isempty(markers)
   % process markers
end

This code will get all markers labeled seizure and EI.

Get markers by values

function main(varargin)
anywave('init', varargin);
cfg = [];
cfg.values = [10 5 512];
markers = anywave('get_markers', cfg);
if ~isempty(markers)
   % process markers
end

This code will get all markers with a value of 10, 5 or 512.

Get markers which target channels

function main(varargin)
anywave('init', varargin);
cfg = [];
cfg.channels =  {'A1', 'A3' };  % get markers targeting channel A1 and/or A3 
markers = anywave('get_markers', cfg);
if ~isempty(markers)
   % process markers
end

Get only markers with a duration

This can be done by specifying options:

function main(varargin)
anywave('init', varargin);
cfg = [];
cfg.options = {'with duration'};
markers = anywave('get_markers', cfg);
if ~isempty(markers)
   % process markers
end
