NAME

mris_smooth

SYNOPSIS

mris_smooth [options] <input surface> <output surface>

DESCRIPTION

This program smooths the tessellation of a cortical surface and write out the first and second order properties after smoothing to the files $hemi.curv (mean curvature) and $hemi.area (area).

POSITIONAL ARGUMENTS

ArgumentExplanation
input surface 
output surface

REQUIRED-FLAGGED ARGUMENTS

None

OPTIONAL-FLAGGED ARGUMENTS

ArgumentExplanation
-a <avgs>specify # of curvature averaging iterations (def=10).
-n <niter>specify # of smoothing iterations (def=10).
-nwdisable writing of curvature and area estimates
-c curvnamewrite curv to ?h.curvname (default 'curv')
-b areanamewrite area to ?h.areaname (default 'area')
-g <norm> <steps>use Gaussian curvature smoothing with norm <norm> and <steps> smoothing steps(-g 20 8 works well for hippo)
-areanormalize area after smoothing
-m momentum 
-w nwritewrite snapshot every nwrite iterations
