Files and Filedescription
RawData.mat - Seperate file = one subject / represents the "raw" as .mat data after epoching and correction of e.g. swapped electrodes in setup.
Field description for RawData:
fsample: sampling rate of 500Hz
sampleinfo: first and last sample index of each trial
trialinfo: 1) trial number, 2) condition coding (see below), 3) sample index at trigger, 4) cue duration (time in seconds)
trial: each cell represents a trial with 65 x samples data points - 65 represents channels (see channel labels, same index).
time: time in seconds for each sample in each trial relative to trigger
label: EEG channel labels
Final_GA.mat - Grand averages used for analyses, cue-locked and pain-locked, as described in the variable names. Cells 1:9 in order as in table above.
Field description fpr GrandAverages:
label = channel labels and order of channels in powspctrm
freq = frequencies in order or powspctrm
time = time in order of powspctrm
powspctrm = power at each subject-chan-freq-time sample
