DFA and PSD estimators #30

Can you briefly explain the differences between DFA and PSD estimators? You mentioned that PSD is highly sensitive to low frequency trends and DFA is more robust to trends, so does that necessarily mean that in BOLD fMRI we always prefer DFA?

I am also very confused about this issue.
