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, -Eric
