<FONT face=Verdana>Hi,<BR> <BR>I am using EEGLAB v9.0.3.4b<BR>Created a STUDY with 9 different conditions and 5 subjects.

It only displayes ERSP for the time points computed above (red text in bold). Indeed it should compute for the range -500 to 1000 ms. Where can I fix this parameter?<BR>Moreover, my data is already bandpass filtered from 1 to 30 Hz but it computes frequencies from 3 Hz to 128 Hz. How to confine computation from 1 to 30 Hz. Although I can display from 1 to 30 Hz.<BR> <BR>Probably I am missing some parameter fixing.<BR> <BR>Any one please help. <BR>thanking you in advance.<BR> <BR><BR>Saim<BR></FONT> </body>
