Bugfixes

• Fix channel selection to respect selection parameter as "seeds" or "targets" when picks is not None in plot_connectivity(), plot_spectral_connectivity(), plot_temporal_connectivity(), and plot_spectrotemporal_connectivity(), by Thomas Binns. (#467)

New features

• Add plot_connectivity(), plot_spectral_connectivity(), plot_temporal_connectivity(), and plot_spectrotemporal_connectivity() for visualising connectivity results, by Thomas Binns. (#460)

• Add missing parameter to control the filling of missing values in dense connectivity matrices in the get_data() method of connectivity containers, for connectivity methods where these values cannot be determined from the lower-/upper-triangular elements, by Thomas Binns. (#461)

• Add 'lower', 'upper', and 'all' as options for indices in connectivity containers and all connectivity-computing functions with an indices parameter, by Thomas Binns. (#461)

• Add automatic filling of missing values in dense connectivity matrices from existing lower-/upper-triangular elements in the get_data() method of connectivity containers, for eligible connectivity methods, by Thomas Binns. (#461)

• Plot multivariate components as separate figures in plot_connectivity(), by Thomas Binns. (#467)

• Speed up spectral_connectivity_epochs() for Morlet wavelet (cwt_morlet) spectra by conjugating each signal once rather than for every connection, by Eric Larson. (#487)

Other changes

• Deprecate method names in favour of the following:

  • phase-slope-index → psi

  • envelope correlation → env_corr and env_corr_orth (depending on orthogonalization)

  • SMI → smi

  • wSMI → wsmi

  • VAR(1) and VAR(p) → var

  • Time-varying VAR(1) and Time-varying VAR(p) → var_dynamic
