We’re still not quite clear on the time bins though – is it the case that the timesout matrix gives the midpoints of the time bins, and if so, why is it that the time bins are not evenly spaced? (They seem to be shifted by 8 or 12 ms.)</span></font></div></div></o:smarttagtype></o:smarttagtype></div></span></blockquote><div><br></div><div><br></div><div>Yes, this is correct. The time bins are not perfectly evenly spaced because if you have 933 original time points (in your data epoch) and generate 200 time estimates for the purpose of time-frequency decomposition, you have to find the closest time point (in the original time array) for each evenly spaced time-frequency time point. </div><div><br></div><div>There is an option in newtimef though where you enter a negative value for the 'timesout' input and it simply subsample the original time space (-4 is considering 1 time point out of 4). This technique does ensure uniform time sampling.</div><div><br></div><div>Arno</div><div><br></div></div></body></html>
