[Eeglablist] pop_newtimef vs newtimef

[Arnaud Delorme]

Dear Ilana,

this is because the meaning of padratio has changed between the "timef" 
and "newtimef" functions for wavelets (not for FFT). The padratio for 
wavelet for timef was not consistent with the padratio for FFT so this 
was corrected in newtimef. The problem is that for the same padratio 
(zero padding), newtimef computes an image with has four times more 
resolution in frequency (and thus is four times slower). Here is another 
message containing the description of other minor differences between 
these functions.
