add time vector to spectrum

Hi,

i am trying to add a time vector to the spectrum using this scrupt but i cannot do it

Could somebody please help me?

thank you very much in advance!

fs=500

timeLimits = [1 28513];%

endtime = 28513/fs;

Time2 = 0:1/fs:endtime

frequencyLimits = [0 1]; % Normalized frequency (*pi rad/sample)

overlapPercent = 50;

%% compute

Diametre_R2_detrend_ROI = Diametre_R2_detrend(:);

Diametre_R2_detrend_ROI = Diametre_R2_detrend_ROI(timeLimits(1):timeLimits(2));

[P,F,T] = pspectrum(Diametre_R2_detrend_ROI, ...

'spectrogram', ...

'FrequencyLimits',frequencyLimits, ...

'OverlapPercent',overlapPercent);

It is not possible to run that (missing data), and nearly impossible to determine what you want to do.

It is certainly possible to use a time vector as an argument to pspectrum. See t in the Input Arguments documentation section.
