Dear Sir/Madam,

My name is Vera Kooiman and momentarily I am working on my master thesis,
measuring EEG in healthy participant walking with a lower-limb dummy
prosthesis.
I am using EEGLAB to analyse my data, but had a question, which I could not
find an answer for online. I am trying to compare two different condition
(normal walking vs walking with a prosthesis) using the ERSP in a STUDY.
But during normal walking, the epoch (step cycle) duration is smaller (1
sec) than during walking with a prosthesis (1.5 sec).  It is not possible
to compare these condition because the epochs are not consistent. But is it
possible to, for instance, scale the ERSP plots to similar lengths and
still compute the statistical differences? We do not wish to scale the
data, because this changes the frequencies in the data and therefore the
result in the ERSP plots.
I hope you can help me with this problem. Thank you in advance.

Kind Regards,
Vera Kooiman
