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 ----------------------------------------------------------------------- ++ Compile date = Oct 13 2022 {AFNI_22.3.03:linux_ubuntu_16_64}
