[FieldTrip] ft_statfun_depsamplesFunivariate

[Schoffelen, J.M. (Jan Mathijs)]

Hi Elisa,

fcdf is probably a function that is in matlab’s stats toolbox. The stat toolbox needs a separate license, which apparently you don’t have. We try to have drop in replacements of the most often used functions, but apparently fcdf is not one of them. (you can read about this here: http://www.fieldtriptoolbox.org/faq/requirements/) At the moment there’s nothing to be done about this.
You either should purchase yourself a license for hte stat toolbox, or write a drop in replacement for the fcdf function.

Best wishes,
Jan-Mathijs

Good morning/evening,

I am trying to compute an Univariate ANOVA with 3 repeated measure levels and I get the following error:


Undefined function or variable 'fcdf'.

Error in ft_statfun_depsamplesFunivariate (line 181)
    s.prob = 1-fcdf(s.stat,s.dfnum,s.dfdenom);

Error in ft_statistics_montecarlo (line 267)
  [statobs, cfg] = statfun(cfg, dat, design);

Error in ft_freqstatistics (line 193)
  [stat, cfg] = statmethod(cfg, dat, design);



I checked both the Fieldtrip and Matlab functions folder and I could not find the fcdf function (only the Student's T cumulative distribution function, tcdf).
Has anyone had this issue?


Thank you for your attention.

Best wishes.

Elisa
