:orphan: .. _ahelp_3dOverlap: ********* 3dOverlap ********* .. contents:: :local: | .. code-block:: none Usage: 3dOverlap [options] dset1 dset2 ... Output = count of number of voxels that are nonzero in ALL of the input dataset sub-bricks The result is simply a number printed to stdout. (If a single brick was input, this is just the count of number of nonzero voxels in that brick.) Options: -save ppp = Save the count of overlaps at each voxel into a dataset with prefix 'ppp' (properly thresholded, this could be used as a mask dataset). Example: 3dOverlap -save abcnum a+orig b+orig c+orig 3dmaskave -mask 'abcnum+orig<3..3>' a+orig Also see program 3dABoverlap :) ++ Compile date = Oct 13 2022 {AFNI_22.3.03:linux_ubuntu_16_64}
