% POP_CHANPLOT - graphic user interface (GUI)-based function with plotting
% options for visualizing. Only channel measures (e.g., spectra,
% ERPs, ERSPs, ITCs) that have been computed and saved in the study EEG
% datasets can be visualized. These can be computed using the GUI-based
% POP_PRECOMP.
% Usage:
% >> STUDY = pop_chanplot(STUDY, ALLEEG);
% Inputs:
% ALLEEG - Top-level EEGLAB vector of loaded EEG structures for the dataset(s)
% in the STUDY. ALLEEG for a STUDY set is typically loaded using
% POP_LOADSTUDY, or in creating a new STUDY, using POP_CREATESTUDY.
% STUDY - EEGLAB STUDY set comprising some or all of the EEG
% datasets in ALLEEG.
%
% Outputs:
% STUDY - The input STUDY set structure modified according to specified user edits,
% if any. Plotted channel measure means (maps, ERSPs, etc.) are added to
% the STUDY structure after they are first plotted to allow quick replotting.
%
% Graphic interface buttons:
% "Select channel to plot" - [list box] Displays available channels to plot (format is
% 'channel name (number of channels)'). The presented channels depend s
% on the optional input variable 'channels'. Selecting (clicking on) a
% channel from the list will display the selected channel channels in the
% "Select channel(s) to plot" list box. Use the plotting buttons below
% to plot selected measures of the selected channel.
% "Select channel(s) to plot" - [list box] Displays the ICA channels of the currently
% selected channel (in the "Select channel to plot" list box). Each channel
% has the format: 'subject name, channel index'.
% "Plot channel properties" - [button] Displays in one figure all the mean channel measures
% (e.g., dipole locations, scalp maps, spectra, etc.) that were calculated
% and saved in the EEG datasets. If there is more than one condition, the ERP
% and the spectrum will have different colors for each condition. The ERSP
% and ITC plots will show only the first condition; clicking on the subplot
% will open a new figure with the different conditions displayed together.
% Uses the command line function STD_PROPPLOT.
% "Plot ERSPs" - [button] Displays the channel channel ERSPs.
% If applied to a channel, channel ERSPs are plotted in one figure
% (per condition) with the channel mean ERSP. If "All # channel centroids"
% option is selected, plots all average ERSPs of the channels in one figure
% per condition. If applied to channels, display the ERSP images of specified
% channel channels in separate figures, using one figure for all conditions.
% Uses the command line functions STD_ERSPPLOT.
% "Plot ITCs" - [button] Same as "Plot ERSPs" but with ITC.
% Uses the command line functions STD_ITCPLOT.
% "Plot spectra" - [button] Displays the channel channel spectra.
% If applied to a channel, displays channel spectra plus the average channel
% spectrum in bold. For a specific channel, displays the channel channel
% spectra plus the average channel spectrum (in bold) in one figure per condition.
% If the "All # channel centroids" option is selected, displays the average
% spectrum of all channels in the same figure, with spectrum for different
% conditions (if any) plotted in different colors.
% If applied to channels, displays the spectrum of specified channel
% channels in separate figures using one figure for all conditions.
% Uses the command line functions STD_SPECPLOT.
% "Plot ERPs" - [button] Same as "Plot spectra" but for ERPs.
% Uses the command line functions STD_ERPPLOT.
% "Plot ERPimage" - [button] Same as "Plot ERP" but for ERPimave.
% Uses the command line functions STD_ERPIMPLOT.
