[Eeglablist] Truncating time valuesl when calculating low frequency ERSP/ITC

[J Saunders]

I searched through the list for an answer and saw something related
(http://sccn.ucsd.edu/pipermail/eeglablist/2010/003231.html).

However, when I implement the suggestion, increasing the pre-stimulus
time, I still get a time values removed warning.

Specific case:

I imported epochs from Spike from -0.25 to 0.25 s into matlab

I then used the following parameters for :

'cycles', [2 10], 'freqs',[10
80],'nfreqs',70,'freqscale','linear','timesout',[-200:4:250]

and EEGlab gives me the warning:

Warning: 82 out of 151 time values were removed (now -136.00 to 136.00
ms) so the lowest frequency could be computed with the requested
accuracy

Why is this happening?  I'm confused about how EEGlab is making this
decision, and what is driving it to remove time points.

Thanks so much for your help.
