Hi Eric   I don’t see any fundamental problem with this analysis. It looks like a regular lme computation. The p-value is essentially zero (to the extent of numeric precision). Even under the null hypothesis p-values distribute uniform(0,1). When signal is present in the data the distribution of

Hello Freesurfer experts, I am getting some unusual results with the lme pipeline, and I would appreciate help with identifying the most likely step in which the problem may have originated. Running lme_fit_FS.m on a single vertex, followed by lme_F on the output of that (stats) yields a p-value
