Dear Freesurfer experts,
I have followed the LongitudinalTutorial with two time points + two
groups and now, after looking at the output of the qdec analysis, I just
want to make sure I haven't made a sign error as for the control group
the difference is as expected around 0 but for the experiment
Hi Vincent,
yes, it is tp2-tp1 / time_delta
so thinning is negative, thickening positive. I'll correct the help
text, the tutorial is right.
It knows about the time point ordering because of the time column.
Best, Martin
