Dear FS Experts,

I am running a longitudinal analyses, and I'd like to use the Linear Mixed Effect framework as even subjects with only 1 time-point can be included into the model.

How do I create the base for a subject with only 1 TP?

Is this the correct approach?

recon-all -base [basename] -tp [subjectid] -all ?

I tried that, but I was met with the following error:

...

mghRead(subjectid/ribbon.mgz, -1): could not open file

Computing euler number

orig.nofix lheno = -436, rheno = -396

orig.nofix lhholes =  219, rhholes = 199
