<div class="moz-cite-prefix">For those having similar problems, note
that FieldTrip (actually Matlab's image function) cannot handle
unequal axis, e.g. a data.freq may not be [1 2 3 4 5 10 15 20].
Therefore, ladies and gentlemen, let me introduce bug number 1729:

type="cite">Dear Fieldtripers ,
<div> I try to plot the TFR with Fieldtrip , but I find the
frequency shift in the plotting when I use different
frequency scale. Please see the attached two examples (4-30Hz
versus 4-100Hz). The TFR within 4-30Hz is centered in alpha
band while it is switched to beta band with the 4-100Hz. scale
. Regarding to the TFR, I calculate it by using an adaptive
sliding time window of four cycles length (Δt = 4/f) and a
Hanning taper for lower frequencies (4–30 Hz), and a sliding
time window of fixed length (200ms) and three orthogonal
Slepian tapers resulting in ±10 Hz smoothing (29) for higher
frequencies (30–100 Hz).</div>
<div> Any suggestion ?<br clear="all">

All the best,</div>
