SYNOPSIS

mri_mask [options] <in vol> <mask vol> <out vol>

DESCRIPTION

This program applies a mask volume ( typically skull stripped ).

POSITIONAL ARGUMENTS

ArgumentExplanation
in volinput volume
mask volmask volume

OPTIONAL-FLAGGED ARGUMENTS

ArgumentExplanation
-xform %sapply LTA transform to align mask to input volume
-invertreversely apply -xform
-lta_src %ssource volume for -xform (if not available from the xform file)
-lta_dst %starget volume for -xform (if not available from the xform file)
-T thresholdthreshold mask volume at threshold (i.e., all values <= T considered as zero)
-bb npadCreate and extract data from a bounding box around the mask. The bounding box is expanded by npad voxels in each direction. npad should be at least 1 to avoid clipping
-abstake abs() before applying threshold
-transfer #transfer only voxel value # from mask to out
-keep_mask_deletion_editstransfer voxel-deletion edits (voxels=1) from mask to out vol
