NAME

mris_curvature

SYNOPSIS

mris_curvature [<options>] insurf

DESCRIPTION

This program will compute the second fundamental form of a cortical surface. It will create two new files <hemi>.<surface>.H and <hemi>.<surface>.K with the mean and Gaussian curvature respectively.

POSITIONAL ARGUMENTS

ArgumentExplanation
<insurf>input surface file

REQUIRED-FLAGGED ARGUMENTS

None.

OPTIONAL-FLAGGED ARGUMENTS

ArgumentExplanation
-wsave curvature files (will only generate screen output without this option)
-maxsave 1st (max) principal curvature in ?h.<surface>.max file
-minsave 2nd (min) principal curvature in ?h.<surface>.min file
-a <avgs>perform <avgs> iterative averages of curvature measure before saving
-nbrs <nbrs>set neighborhood size to nbrs

OUTPUTS

OutputExplanation
insurf.hmean curvature file
insurf.Kgaussian curvature file

EXAMPLE 1

mris_curvature lh.pial
Compute the curvature and do not produce output files.

EXAMPLE 2

mris_curvature -w -a 10 lh.pial
Smooth 10 iterations and produce output files.
