NAME

mri_fill

SYNOPSIS

mri_fill [options] <input MR directory> <output MR directory>

DESCRIPTION

This program creates hemispheric cutting planes and fills white matter with specific values for subsequent surface tesselation.

POSITIONAL ARGUMENTS

ArgumentExplanation
<input MR directory>input directory
<output MR directory>output directory

REQUIRED-FLAGGED ARGUMENTS

None

OPTIONAL-FLAGGED ARGUMENTS

Where options

ArgumentExplanation
-T <threshold>specify fill_holes threshold (default=1)
-xform <xformname>use xform dst offset to get an accurate Talairach volume
-segmentation <filename>aseg volume used to perform fill
-atlas <filename>specify atlas to use for auto-filling
-fillvenfill ventricles

Seed point options in Talairach coordinates

ArgumentExplanation
-C <x> <y> <z>Talairach coords of the seed for the corpus callosum
-P <x> <y> <z>Talairach coords of the seed for the pons
-lh <x> <y> <z>Talairach coords of the white matter seed for the left hemisphere
-rh <x> <y> <z>Talairach coords of the white matter seed for the right hemisphere

Alternative seed point options in voxel coordinates

ArgumentExplanation
-CV <x> <y> <z>voxel coords of the seed for the corpus callosum
-PV <x> <y> <z>voxel coords of the seed for the pons

OUTPUTS

OutputExplanation
filledThe filled volume for the cortical reconstruction- used for subsequent surface tesselation.

EXAMPLE 1

mri_fill SUBJECT/mri/wm/. SUBJECT/mri/filled

Takes a subjects wm volume as input and uses this to find cutting planes to seperate the hemispheres and remove the brainstem, and fills hemispheres with specific values as filled volume output.
