[Eeglablist] dftfilt3: timesupport variable fixed

I have a question about time-frequency analysis with newtimef() and wavelet
Wavelets are actually calculated in dftfilt3.m function, where the variable
"timesupport" seems to be fixed at the value 7.
If I well understand, this parameter influences the wavelet temporal length.
When recalled from timefreq(), "timesupport" cannot be changed by user.
I wonder why it was fixed exactly at 7 and how reducing it could affect the
For example, in my data (1800 ms, sampling rate = 500 Hz), using such a
large time standard deviation, results in a too large wavelet window and
half of the epoch time becomes lost.
Reducing it at 2 or 3 seems to do the trick, but I would like to understand
sides effects (if any).
Thank you for any clarification!
