Hello,
I noticed that Freesurfer's latest release offers an expert option "added -first_wm_peak flag to mris_make_surfaces, which may aid accurate
more white matter surfaces especially in heavily myelinated areas like
visual cortex on data that is higher res than 1mm. enable the flag via
an expert.opts file."
Are these expert options doing something similar to what was done in Lüsebrink, Wollrab, Speck, 2013 in
NeuroImage, in which they " conforms the data to the minimum voxel size, which is equal in all directions if data with an isotropic resolution is used"
