Hello freesurfer, I am trying to run mri_glmfit with the --table flag. My aparc_lh_thick_stats.txt contain entorhinal and parahippocampal thickness values for 32 subjects. I ran the glm command and received an error. Please, how can i solve this issue? I have included my command, fsgd file, contrast matrix and error below. Thanks Best, Paul
