Dear Alfonso,

Thank you very much for your very helpful reply!

Yes indeed the rsHRF does its own denoising steps to possibly reduce biases for hrf estimation. These denoising steps are deactivable but doing so will result in biased estimation according to the authors (I tried and it was bad ;-) ).

Ok I will reimport the functionals as you suggest, but how is it possible to skip the denoising step? Simply by not clicking on "Done"? But then will the new functionals be used instead of the one denoised by CONN? Sorry to ask but I'm not sure how to disable CONN's denoising, I never did that before :-p

Thank you again Alfonso!
Best regards and cheers from Belgium!
