Initial software release following publication of Corcoran et al.'s automated IAF quantification preprint. Includes functions for performing Savitzky-Golay filtering and differentiation of power spectrum in order to estimate individual alpha frequency measures (peak alpha frequency and alpha frequency centre of gravity). See the included tutorial files for a demonstration of how these functions can be integrated within EEGLAB to derive IAF estimates from preprocessed EEG data. Package also includes functions required to replicate the simulation-based analyses reported in the preprint.
