External Email - Use Caution        

Dear experts:

I have a doubt about finding the medial wall mask of a subject. 


Would this be ok?

 

mri_label2label --srclabel lh.cortex.label --trglabel lh.cortex.label --outmask lh.cortex.mask.nii.gz --regmethod surface --hemi lh --srcsubject 25633 --trgsubject 25633

 

fscalc lh.cortex.mask.mgz not -o lh.medialwall.mask.mgz 

 

mri_convert lh.medialwall.mask.mgz lh.medialwall.mask.gii



If I use mris_decimate to downsample the surface does it change anything of previous and how should I proceed in that case to change it?


Best, 

Rene Andrade.
