Dear SPMers,
I'm running time-frequency analysis on my MEG data - I have a total of
60, 10s-long trials/block and I'm looking at the 1:60 Hz frequency
range. I then baseline correct using rescale, and finally average the
data for each condition. There are 4 conditions, so ~15
trials/condition in each block, and for some reason the averaging
seems to take a really long time - probably about 6 hours, sometimes
more, whereas the tf analysis takes about 20 mins. Any idea why that
might be?
I should also mention that I downsampled the data to 300 Hz.
Thanks!
Ivana
