Dear all,

I have a problem with randomise. I have two groups of patients controls and patients and i want to integrate the age and gender in the matrix. When i run the randomise without these parameters everything goes well. When i use age and gender i have an error type like this:

Data loaded
> 76 permutations required for exhaustive test of t-test 1
> Doing all 76 unique permutations
> Starting permutation 1 (Unpermuted data)
> ERROR: Program failed
> 
> An exception has been thrown
> Error: tfce requires a positive deltaT input

Do u have any idea what i am doing wrong?

Thanks in advance
