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.
