3dMVM error

Hello!

Long time listener…

I’m using 3dMVM. Here I am interested in the age by diagnostic group interaction as it predicts the brain outcome measure. I am getting the following error:

Error in [.data.frame(lop$dataStr, , jj) : undefined columns selected
Calls: process.MVM.opts → [ → [.data.frame
Execution halted

Here is the (truncated) command. Do I need the -glt options? I’m not sure where to start…

Thanks for the help!

Change the following line

-qVars “age+sex+educ+movement” \

to

-qVars “age,sex,educ,movement” \

3

Thank you, this worked!

Hello,

Sorry if this is a duplicate. I tried posting but I don’t see it. Anyway, I just wanted to solve one additional problem. I am interested in the Age main effect, specifically the direction of it. The F test is reported, but it doesn’t provide the slope.

I assume I can run the following?

'DxGroup : 1ADHD -1Typical Age : ’
'DxGroup : 1ADHD Age : ’
'DxGroup : 1Typical Age : ’

which will give me everything I want for Age? Age is centered on the mean.

Does this look right?

Yes, those 3 lines would help you parse the age effect in terms of its directionality.
