Dear all,
I am trying to perform an statistical analysis from FA Maps of two groups with 9 subjects each one using randomise function.
randomise is throwing an error at me after stalling at permutation 2. "Warning: tfce has detected a large number of integral steps. This operation may require a great deal of time to complete.
See attached more information.
Any suggestion about the issue?
Thanks in advance,
Alex
The call to the function is:
randomise -i <input> -o <output> -d <design.mat> -t <design.con> -n 5000 --T2 -V
The design matrix is:
/NumWaves 2
/NumPoints 18
/PPheights 1.000000e+00 1.000000e+00
/Matrix
1.000000e+00 0.000000e+00
1.000000e+00 0.000000e+00
1.000000e+00 0.000000e+00
