Hi,
It is standard deviation units which is in fact a very clever way of expressing the signal fluctuation (much better than percentages of change, I would say). So it is centered around zero with a SD of 1 across the entire time-series.
Cheers-
Andreas

Betreff: [FSL] y-axis of timecourse output in MELODIC
Hi!
Thank you so much Christian for your answers to my last questions-they were most helpful and have given me a lot to think about.
I am almost embarassed to ask this one, but I want to be sure that I am interpreting what I am seeing correctly. What are the units on the y-axis of the timecourse output in MELODIC on the report page (the top plot that says Timecourse (in seconds); TR=x)? Thank you!
Christina
