[Eeglablist] If you want to run 3 Hz 3 cycle wavelet but only have epochs shorter than 3 second...

[Arnaud Delorme]

We had debate about the use of this plugin. I personally think that if you have short epochs (and have lost the continuous data), then the only thing you could do to artificially make them larger is pad them with 0. However, 0-padding can add artifacts at boundaries.

Makoto's solution was to add real data (from other data epochs). I think this is debatable and you need to be aware that your ERSP solution will be valid only within a specific time range at low frequencies.

Makoto, maybe you could implement the 0-padding as well so people have more choices?

I was unable to provide a reasonable solution at that time, but now alpha version (i.e. use at your own risk) of it was created. This is a plugin for EEGLAB. Sorry I don't remember who asked the question. Hopefully they find this post. If you find a bug let me know.
