the newest version of fieldtrip (14th june 2016) calls ft_nargin the previous version of fieldtrip (for example friday 10th of June 2016) does not (but calls "nargin") cfg = []; cfg.correctm = 'no'; cfg.method = 'analytic'; cfg.statistic = 'depsamplesT'; cfg.latency = [0.2 0.7]; cfg.frequency = [8 12]; %, cfg.avgovertime = 'yes' ;% cfg.avgoverfreq = 'yes'; % Nsub = 20;,:) = [ones(1,Nsub) 2*ones(1,Nsub)]; (2,:) = [1:Nsub 1:Nsub]; cfg.ivar = 1; cfg.uvar = 2; Stat_Letter_facevssign_812_27= ft_freqstatistics(cfg, con1{:},cond2{:}); ERROR : (newest fiedltrip version only ) Undefined function or variable 'ft_nargin'. Error in ft_preamble_init (line 34) if ft_nargin==0 Error in ft_preamble (line 56) evalin('caller', ['ft_preamble_' cmd]); Error in ft_selectdata (line 89) ft_preamble init % this will reset ft_warning and show the function help if nargin==0 and return an error Error in ft_freqstatistics (line 117) [varargin{:}] = ft_selectdata(tmpcfg, varargin{:});

Hi Fanny does the problem persist if you close matlab and start it again? I suspect it to be due to a change in one function, and that MATLAB keeps another related function in memory without updating it, although the code should be "recompiled" as well. Robert

(In reply to Robert Oostenveld from comment #1) no, I can confirm myself that with a new matlab session it fails.

(In reply to Robert Oostenveld from comment #2) [master f7de187] FIX - hotfix for nargin/ft_nargin bug, primarily in ft_selectdata but also in other functions. The cause was that these functions were not yet adjusted to the latest state of ft_preamble handling. See 32 files changed, 129 insertions(+), 40 deletions(-) The obvious error was that ft_selectdata was not yet adjusted to the latest state of the ft_preamble functions, and apparently most other functions in sub-directies (utilities, contrib) were not. The nargin change I made this afternoon assumed that all code was according to the latest standards, and therefore revealed the inconsistency in other functions.
