mris_anatomical_stats - measures a number of anatomical properties

Synopsis

mris_anatomical_stats [options] <subjectname> <hemi> [<surfacename>]

<subjectname>	subject name
<hemi>	hemisphere

surface name

none

-i <low thresh> <hi thresh>	only consider thicknesses in the specified range.
-l <label file>	limit calculations to specified label
-t <thickness file>	use specified file for computing thickness statistics
-a <annotation file>	compute properties for each label in the annotation file separately
-b	tabular output
-f <tablefile>	table output to tablefile (different format than -b). Must use -a or -l options to spec input.
-log <logfile>	Write stats to file named log
-nsmooth <#>	Smooth thicknessmap # of iterations before using it
-c <ctab file>	Output annotation files's colortable to text file
-noglobal	Do not compute global brain stats
-th3	Compute vertex-wise volume by dividing each obliquely truncated trilateral pyramid into three tetrahedra

Tabular output includes the following:

Data column	units	Comments
Structure Name	NA
Number of Vertices	unitless
Surface Area	mm^2	total surface area
Gray Matter	Volume mm	total gray matter volume
Average Thickness	mm	average cortical thickness
Thickness Std Dev	mm	+- standard error (mm)
Integrated Rectified Mean Curvature	mm^-1
Integrated Rectified Gaussian Curvature	mm^-2
Folding Index	unitless	a la Van Essen
Intrinsic Curvature Index	unitless	a la Van Essen
