I am running the ft_freqstatistics using the actvsblT option, so as to
statistically test activation period with baseline activity. For this,
I followed the "Within trial experiments" tutorial in fieldtrip
(http://fieldtrip.fcdonders.nl/tutorial/cluster_permutation_freq#within_trial_experiments).
The tutorial emphasizes that one should select equal length time
windows. However, the number of trials in both conditions (activation
and baseline) remains unequal. Therefore, when I run ft_freqstatistics
with the design mentioned in the tutorial (inserting only the number
of trials of the activation condition), I receive the following error
message:
"the number of observations in the design does not match the number of
observations in the data"
Is there an error in the turorial, or is the script intended to create
two frequency output-files, with different total number of trials.
Thanks in advance,
Yoni
