Longitudinal Analysis Error
Hi Admins,
Thank you for creating such a nice tool!
I’m running an analysis of a longitudinal study. There are two groups with three time points and an attrition rate that causes the groups to be uneven all time points. They’re different by a few subjects at each point.
I setup 6 Conditions to assign to each group (3 time points x 2 groups) and assign them the functional data accordingly. I check the “allow missing data” box in the setup as well.
The preprocessing, denoising and 1st level was error free. However, I get an error when I run the 2nd level analysis to compare BETWEEN groups. For example, group 2 > group 1 for any of the time points, I get an “exceed matrix size” error. I also notice that the design matrix counter in the tool goes to 0. The tool works fine when I compare within groups.
Can you help me? Did I make a mistake in settings up the conditions?
Thank you,
Pavel
