If your sequence is not meant to be periodic (i.e., if after one minute there is no reason why the signal should start back at the beginning right away), then you should do zero-padding. And while you zero-pad, you can zero-pad to a sequence that is a power of two, thus preventing awkward factorizations.
Zero-padding won't help with the non-periodicity, will it? For that you may want to window instead. Stéfan
