Multi-taper triggered time-frequency spectrum - binned point process
Usage:
[S,t,f,R,Serr]=mtspectgramtrigpb(data,E,win,tapers,pad,Fs,fpass,err,trialave,fscorr,t)
Input:
data (single channel data in a column vector) -- required
E (event times) - required
win (in the form [winl,winr] i.e window around each event
required
movingwin (in the form [window,winstep] i.e length of moving
window and step size) -
required
Note that units for the windows have
to be consistent with
units of Fs
tapers (precalculated tapers from dpss, or in the form [NW K] e.g [3 5]) -- optional. If not
specified, use [NW K]=[3 5]
pad (padding factor for the FFT) - optional. Defaults to 0.
e.g. For N = 500, if PAD = 0, we pad the FFT
to 512 points; if PAD = 2, we pad the FFT
to 2048 points, etc.
Fs (binning frequency) - optional. Default 1.
fpass (frequency band to be used in the calculation in the form
[fmin fmax])- optional.
Default all frequencies between 0 and Fs/2
err (error calculation [1 p] - Theoretical error bars; [2 p] Jackknife error bars,
[0 p] or 0 - no error bars) - optional. Default 0.
trialave (average over trials when 1, don't average when 0) -
optional. Default 0
fscorr (finite size corrections, 0 (don't use finite size corrections) or 1 (use finite size corrections) - optional
(available only for spikes). Defaults 0.
t (time grid over which data is specified). optional. Default [0:length(data)-1]/Fs
Output:
S (triggered time-frequency spectrum in form time x frequency x channels/trials)
t (times)
f (frequencies)
R (spike rate)
Serr (error bars)
