Hi Sophie,
it's a bit hard to tell, but maybe one option would be to try fitting the model
with just a random-intercept effect instead of both random-intercept and
random-slope effects.
I.e. using [1] instead of [1 2] for the Zcols argument to lme_m

installed R2023b separately via a Mathworks matlab installer. We do
provide a script

using the LME Matlab (R23b) Toolbox distributed within Freesurfer (7.4.1) in
