Actually, this will cause a problem. I've closely looked at the script, and it appears that your suggestion is correct:
I just tried something using the files in the bug report, as well as with the up-to-date 1.3 repository (r9001)... I modified line 303 of the script from: self.model_selection(modsel_pipe='final', dir=self.base_dir + 'aic') to: self.model_selection(modsel_pipe='aic', dir=self.base_dir + 'aic') With this change, model 'm8' is eliminated and model 'm1' is selected instead.
This data pipe is for AIC model selection and the results go into the 'aic' directory. This is followed by the 'opt' data pipe for diffusion tensor optimisation. So I'll make the change to the repository. But could you check if all works with the changes that were made to the 1.3 line? I think these changes were logical, but there is a regression causing a system test to fail. Cheers, Edward
