Null Distributions

[Antonin_Skoch]

Dear @cbajada,

this thread and therein recommended paper might be helpful for you:

Just iFOD1 and iFOD2 works, FACT not

Ah sorry, I forgot about that one in my response: The nulldist / nulldist2 algorithms are supposed to be noisy; that’s their defining attribute (“Null Distribution”). I would suggest reading the relevant article that is cited in the tckgen command’s reference section.
