I see that generating the hippocampal subfields in the longitudinal pipeline has its own script (segmentHA_T1_long.sh), but am not seeing a corresponding script or command to do the same for the hypothalamic subunits. Would simply running mri_segment_hypothalamic_subunits on my subject_session

Hi, I am running glmfit on some functional data (using ces.nii.gz surface files as input) using ROIs and the --mask argument, that I plan to later submit to glmfit-sim for small volume correction. I have some rois that are subcortical and some that are surfaces. For the glmfit run within the
