Hey @Pavan Kumar Reddy Yannam, the error means MATLAB can't find a variable or function named tt when it tries to execute line 7 of your plot_FB_triggers.m file.

Can you please verify the checklist below:

1. Is tt defined before line 7?

• Look at the lines before line 7 in plot_FB_triggers.m. Is there a line that assigns a value to tt? For example:

tt = (1:100)'; % Example: create a time vector
% Or, is it loaded from somewhere?
% load('my_data.mat', 'tt');

2. If plot_FB_triggers is a function, is tt passed as an input argument?

function plot_FB_triggers(tt, can) % <--- tt must be an input
    % ...
    Plot(tt, can.DATDev.FB_Triggers.ctimeu, ...
end

3. Typo? Double-check the spelling of tt. Maybe it's t or time or something else in your code.

Hope it helps.
