Hi pt,
I followed your advice,
I tested my human dataset with 'scale' and without and I not obtain the same results, especially for the comparison of aged versus young.
With 'scale', the difference of ALLF in the DMN seems to not be less important.
Since I am not sure how scale would affect the results, do you think that scaling is recommended for comparison between groups? does it remove part of the information that might be useful to calculate ALLF?
thank you very much!
