Dear Field-trippers I recently ran some time frequency analysis using the wavelet method. I was surprise to see that whereas I asked for a step of 1Hz, it was not the case every alternate step (for foi=2:1:10 ; I got [2 3.2 4 5.2 6 7.2 8 9.2 10]), and it was also the case when I changed the toi (2.5, 1.5 with constant trials length of 2.5 sec and sampling freq 1000Hz). I found a kind of explanation following the faq ( Still it is not clear to me why this refers to Fourier transform. From my (none specialist) point of view it is possible to produce a wavelet of any size (Hz;Dt). It is clear that there is some limitations based on the duration of the epochs and the number of time points. But in the present case it shouldn't be a problem, is it? Would be please if someone can help me with this issue. Thanks in advance Manuel -> this also holds for the corresponding faq about mtmconvol
