Hi Jeffery,


I only included the symptom variable, unfortunately, there was still the same error showing in Matlab. The following is Matlab error message:

Running permutation analyses for contrast/F-test 1 ...
Error using regstats (line 124)
The design matrix has more predictor variables than observations.

Error in GTG_runpermanalyses_GUI>GTG_GLM (line 4261)

Thank you very much for kind help,
