Spectral Group Compare
Group comparison of time courses is done by comparing the power
spectra between the groups at different frequency bins. Bins are labeled using
the variable DEFAULT_TR_SPECTRAL_GROUP_COMPARE in "icatb_defaults.m". The results
of the power spectra comparison is saved in a MAT file having suffix
'*comparison_frequency_bins.mat'. The variables stored in the
file are as follows:
- mean_power_group1 - Mean power for group 1.
- mean_power_group2 - Mean power for group 2.
- tValues - T-values. This variable is used for plotting
the bar graphs.
- pValues - p-values.
Figure 1 shows the T-values of the components in groupings of four at different frequency bins.
