String identifying the subject for the data set. String giving the start time in 24 hour hh:mm:ss format. String giving the start date of data set in dd-mmm-yyyy format. If an EEG structure is passed to getBlinkerDefaults, the default value is EEG.srate.
The possibilities are to use a specific set of channel numbers, a specific set of channels identified by their labels, or a specific set of independent components identified by their position in the mixing matrix.Ī positive scalar giving the sampling rate of the signal in Hz. String specifying the type of signals from which to extract blinks. The numbers of the channel numbers to try as potential signals if signalTypeIndicator is ‘UseNumbers’. Params.blinkerSaveFile = 'D:\ARL_BCIT_BLINKS\AllUnrefBlinkSummary.mat' The following example starts with a default params structure and then overrides some of the values related to controlling the output and to data set metadata: Params = checkBlinkerDefaults(struct(), getBlinkerDefaults(EEG)) When you are going to override defaults it is good to start with a complete params structure with all of the default values filled in: Usually you will want to override the defaults. The previous example uses all of the default values, including defaults for metadata such as the subjectID.

Run BLINKER without manual intervention, using all of the default parameters: Run BLINKER outside of EEGLAB but bring up a GUI to set parameters: While it is possible to run BLINKER using the low-level functions, the easiest way to run BLINKER is to put your EEG dataset into an EEGLAB EEG structure. While it is possible to run BLINKER as a plugin from EEGLAB, BLINKER is meant to be run in batch processing mode to analyze large collections of EEG. However, these are all available for setting if you wish to run BLINKER from a script as described in the next section. BLINKER is designed to be run without manual setting of internal algorithm parameters. The BLINKER pipelineĬan be found under the EEGLAB Tools submenu:Īfter selecting the “Run Blinker” option, you will see a menu that allows you to set dataset metadata and options for saving BLINKER output. Load an EEG dataset to be processed using the Load dataset submenu under the File menu of EEGLAB. When you start EEGLAB, BLINKER will be available.

You can install BLINKER as an EEGLAB plugin by unzipping the blinker1.0.0 directory into the plugins directory of your EEGLAB installation. Regardless of how you run BLINKER, EEGLAB will need to be in your path.

To run in standalone mode, simply download the BLINKER code, found in the EEG-Blinks github repository, and add the blinker directory and all of its subdirectories to the MATLAB path.
The BLINKER pipeline can be run in two ways - as a standalone toolbox or as an EEGLAB plugin. This research was sponsored by the Army Research Laboratory and was accomplished under Cooperative Agreement Number W911NF-10-2-0022.

Various high-level BLINKER wrapper functions assume that the EEG data is provided as an EEGLAB EEG structure and that channel locations are provided in the EEG.chanlocs structure. The BLINKER pipeline relies on the MATLAB Signal Processing toolbox, the MATLAB Statistics toolbox and EEGLAB, a freely-available MATLAB toolbox for processing EEG. Calculate the ocular indices for the “used” signal.Calculate the blink properties and blink shapes for the “used” signal.Select the “best” candidate signal as the “used” signal.Reject signals with low signal-to-noise (SNR) ratios.Calculate landmarks of potential blinks.Extract potential blinks of each candidate signal.Parameters describing what to save or display.Parameters describing data set metadata.BLINKER is designed to be run in a completely automated way. BLINKER also has facilities for merging blinks calculated from different source signals and for plotting individual blinks to facilitate manual evaluation and synchronization of EEG with video and eye tracking. BLINKER takes as input an arbitrary number of signals, which can include ordinary EEG channels, EOG channels and independent components (IC), determines which signals have acceptable blinks, and then selects the “best” candidate blink signal to further characterize blink shapes and properties. tar.gz Introduction to BLINKERīLINKER and associated tools form an automated pipeline for detecting eye blinks in EEG and calculating various properties of these blinks.
