Hi Shani, it looks like your commands are right. How are you judging
that the mask is thicker? What is the resolution of the DTI volume? When
you binarize in a coarser space, you'll naturally not get it to line up
with the surface, and the binary mask will naturally be thicker.

Hi Glen, I think there is some confusion here about what this conversion

way the information is stored, but it is still surface data. SPM/MRIcron

The subfield module uses a different, independent method to segment the
hippocampus, and consistency with ASEG results is not explicitly
enforced. That said, the subfield module is inialialized with the ASEG,

The first cmd (mris_register, or use the surfreg script) will create a
new registration file in subject/surf. Make sure you don't overwrite the
original one (?h.sphere.reg). mris_preproc will just create a single
output file with all of your subjects' thickness data (unless you use
--qcache)
First check the value of the BBR cost function. If it is over .8, then
something is wrong. To check whether it is an LR flip, you can flip the
volume LR and re-run the registration to see if it gets better.

You do not need another one unless you think that the brain has changed
in some way between when you collected the anat and the func. Also, if
