[Eeglablist] Time values output from timefreq and excluding epochs based on event markers

Hi All,

1. Is there any way to get uniformly distributed time values when running
wavelet decomposition using timefreq. Here's my setup:

g.tlimits = [-500 3500];
g.timesout = [1500];
g.freqs = [13:1:30];
g.cycles = linspace(4,8,length(g.freqs)) ;
g.padratio = 2;

Using user-defined cycle for each frequency
Generating 1500 time points (-328.9 to 3326.9 ms)
Finding closest points for time variable
Time values for time/freq decomposition is not perfectly uniformly
The window size used is 171 samples (342 ms) wide.
Estimating 18 linear-spaced frequencies from 13.0 Hz to 30.0 Hz.

With the above, I am getting time values that are sometimes 2 ms apart,
sometimes 4 ms apart.

2. Is there any quick way of excluding epochs based on event markers? For
example, I want to extract epochs that have the marker 'S1' but not if the
epochs also contain the marker 'S2'?

Thank you in advance!
