nirs.core.Data
This is the main class for holding time-series information.
Data with properties:
description: [] This field holds a description of the data. Usually the filename
data: [] This is the actual data time course matrix
probe: [] This holds a nirs.core.Probe object
time: [] The time vector specifying the sample times for the data
Fm: 0 Used for frequency-domain NIRS (for CW; Fm=0). Modulation frequency in MHz
auxillary: [1×1 Dictionary] Field to hold any additional information including extra time courses
stimulus: [1×1 Dictionary] Field to hold the stimulus information
demographics: [1×1 Dictionary] Field to hold information about the subject/file demographics
Fs: NaN (read-only) Sample frequency computed from the time vector
Example usage:
raw = nirs.testing.simData; % This simulates a sample data object
raw.draw(5); % This will draw the time course of the 5th channel
% You can also use
raw.gui; % to draw an interactive view
% The stimulus information is set in the stim field
disp(raw.stimulus);
stim = raw.stimulus(‘A’);
disp(stim);
