Could i define baseline with one value(the end of baseline)?

''baseline' = Spectral baseline end-time (in ms). NaN --> no baseline is used.<br>
% A [min max] range may also be entered<br>
% You may also enter one row per region for baseline<br>

Hello,<br>
<br>
i have a problem when i try to compute ERSP. The only values that i<br>
can define for Baseline are 0 or NaN ...when i am trying to define a<br>
range of values like [-400 -200] i have the following error:<br>
<br>
" There are no sample points found in the default baseline. This may<br>
happen even though data time limits overlap with the baseline<br>
period(because of the time-freq. window width). Either disable the<br>
baseline, change the baseline limits."<br>
<br>
Could someone ,please, help me?<br>
<br>
Thank you in advance,<br>
Konstantina<br>
