Hello Freesurfer experts,

The lme_mass_vw script runs for a long time and outputs info into the matlab terminal.  Most look like this:

Location #####: Algorithm did not converge.  Initial and final likelihoods: ###, ###

Running this script, for almost every line, the initial and final likelihoods are "Inf".  Is this indicative of a problem?

Getting these results made me wonder if the Y-input was built properly.  Using mris_preproc and mri_surf2surf to smooth, we tested 10mm smoothing and no smoothing in addition to the 30mm smoothing we had been doing originally.  The results:

smoothed to 30 ~ almost every likelihood = Inf, Inf
smoothed to 10 ~ some (1 in 5? 10?) likelihood = Inf
not smoothed ~ no instances of likelihood = Inf, Inf

Thanks,
