++ 3dIntracranial: AFNI version=AFNI_2011_12_21_1014 (Dec 16 2015) [64-bit] ++ Authored by: B. D. Ward ++ 3dSkullStrip is usually superior to 3dIntracranial 3dIntracranial - performs automatic segmentation of intracranial region.

This program will strip the scalp and other non-brain tissue from a high-resolution T1 weighted anatomical dataset.

** Nota Bene: the newer program 3dSkullStrip should also be considered ** for this functionality – it usually works better.


Usage:

3dIntracranial

-anat filename => Filename of anat dataset to be segmented
[-min_val a] => Minimum voxel intensity limit
Default: Internal PDF estimate for lower bound
[-max_val b] => Maximum voxel intensity limit
Default: Internal PDF estimate for upper bound
[-min_conn m] => Minimum voxel connectivity to enter
Default: m=4
[-max_conn n] => Maximum voxel connectivity to leave
Default: n=2
[-nosmooth] => Suppress spatial smoothing of segmentation mask
[-mask] => Generate functional image mask (complement)
Default: Generate anatomical image
[-quiet] => Suppress output to screen

-prefix pname => Prefix name for file to contain segmented image

** NOTE **: The newer program 3dSkullStrip will probably give
better segmentation results than 3dIntracranial!

Examples:

3dIntracranial -anat elvis+orig -prefix elvis_strip

3dIntracranial -min_val 30 -max_val 350 -anat elvis+orig -prefix strip

3dIntracranial -nosmooth -quiet -anat elvis+orig -prefix elvis_strip
