DPARSFA 2.3: Correct "Slice Order" values for sequential (ascending) acquisition

Dear DPARSF users and developers,

Could you please confirm that the values I am enering are correct?

I have 200 BOLD volumes per subject, 40 slices acquired in a sequential (ascending) order. 
Slice numbering starts at 0, therefore I should enter:
Slice number: 200
Slice order: [0:39] (or should we still start from 1? i.e. [1:40])
Reference Slice: 0 (or 1?)

Am I right?

Thank you very much for your time!

Alex
