Hi Dhruman,
there is no default threshold - it's determined automatically. Nick: can
you point out the flags for setting the segmentation threshold (this will
disable the automatic estimation).
cheers,
Bruce

Hi,
I am interested in changing the white matter low limit for the
segmentation step. For this I typed the following in the command prompt:
recon-all -subjid <subjectname> -autorecon2 -seg-wlo <low limit value>
this gave me an error stating that it could not recognize -seg-wlo flag.
I was wondering if there is a mistake in writing the command?
I would also like to know if there is any default lower limit for gray
matter threshold used my mri_segment? If so what is it and can it be
changed?
Thank you.
