If I call the following routines in a row, ft_warning off; cfg = ft_definetrial(cfg); data = ft_preprocessing(cfg); I get the following error trace, when ft_preprocessing is executed: Error using isstruct Not enough input arguments. Error in mergeconfig>mergeconfig_helper (line 49) elseif isfield(input, fn) && ~isstruct(default.(fn)) Error in mergeconfig>mergeconfig_helper (line 53) input.(fn) = mergeconfig_helper(input.(fn), default.(fn)); Error in mergeconfig>mergeconfig_helper (line 53) input.(fn) = mergeconfig_helper(input.(fn), default.(fn)); Error in mergeconfig>mergeconfig_helper (line 39) input(j) = mergeconfig_helper(input(j), default(j)); Error in mergeconfig>mergeconfig_helper (line 53) input.(fn) = mergeconfig_helper(input.(fn), default.(fn)); Error in mergeconfig>mergeconfig_helper (line 53) input.(fn) = mergeconfig_helper(input.(fn), default.(fn)); Error in mergeconfig (line 12) input = mergeconfig_helper(input, default); Error in ft_preamble_init (line 55) cfg = mergeconfig(cfg, rmfield(ft_default, 'preamble')); Error in ft_preamble (line 85) evalin('caller', full_cmd); Error in ft_preprocessing (line 182) ft_preamble init If I add a cfg = rmfield(cfg, {'notification'}); between ft_definetrial and ft_preprocessing or if I omit ft_warning off; then the error doesn't appear. So I think, the error is produced by the new notification system. It was not not possible for me to find the source of this error in a short time and fix it, therefore I reported the error here

Hi Daniel, I have seen the problem before, and have tried to address it already back then. It has to do with the state of the notification system which is maintained between calls in the global ft_default variable. If I do global ft_default ft_default = [] ft_warning off cfg = []; cfg.dataset = 'test_playback.edf'; cfg.trialdef.triallength = 1; cfg.trialdef.ntrials = inf; cfg = ft_definetrial(cfg); data = ft_preprocessing(cfg); I cannot reproduce it. Could you try this (with one of your data sets)?
