[FieldTrip] indepsamplesF produces NaN

[Enya Weidner]

Hi everyone!

I am currently trying to run statistical analyses on timelocked data by comparing the values of three different experimental conditions with help of an F-Test. I tried using the “indepsamplesF” function and it runs smoothly with no errors (there is a warning when I run the montecarlo method saying: “no clusters were found in the observed data”) but produces NaNs in the probabilities and test-statistics. This happens for both the “montecarlo” and the “analytic” method. If I run just simple t-Tests I am getting interpretable results. Does this simply indicate that there are no significant differences between conditions? Wouldn’t there still be an F-value indicating such a result?  

Any ideas as to why this happens?

Thanks a lot in advance for your help!
