Dear FreeSurfers,

I am processing MEMPRAGE images:

1) I use the RMS (of the echoes) output from the scanner 2) the echoes were converted to mgz format [memprage_echo1(to4).mgz], conformed to 256³ , 1mm isotropic, and no further processing. 3) I ran the mris_make_surfaces -dura memprage_echo%d.mgz 4 subjid lh/rh, and got new files as output (?h.white_addedname, ?h.pial_addedname etc)

However, I expected to have more of the dura discarded from the ?h.pial boundaries as what I am getting

May I be missing something in the processing of this type of images? How can I improve the output?

Thank you in advance,

Gina
