% POP_ERPPARAMS - Set plotting and statistics parameters for cluster ERP
% plotting
% Usage:
% >> STUDY = pop_erpparams(STUDY, 'key', 'val');
%
% Inputs:
% STUDY - EEGLAB STUDY set
%
% Input:
% 'topotime' - [real] Plot ERP scalp maps at one specific latency (ms).
% A latency range [min max] may also be defined (the
% ERP is then averaged over the interval) {default: []}
% 'filter' - [real] low pass filter the ERP curves at a given
% frequency threshold. Default is no filtering.
% 'timerange' - [min max] ERP plotting latency range in ms.
% {default: the whole epoch}
% 'ylim' - [min max] ERP limits in microvolts {default: from data}
% 'plotgroups' - ['together'|'apart'] 'together' -> plot subject groups
% on the same axis in different colors, else ('apart')
% on different axes. {default: 'apart'}
% 'plotconditions' - ['together'|'apart'] 'together' -> plot conditions
% on the same axis in different colors, else ('apart')
% on different axes. Note: Keywords 'plotgroups' and
% 'plotconditions' may not both be set to 'together'.
% {default: 'together'}
% 'averagechan' - ['rms'|'on'|'off'] average data channels when several are
% selected ('on') or compute root mean square ('rms').
