lobes_to_volumes.pl

compute lobe volumes from a lobe-segmented MINC volume

lobes_to_volumes.pl <lobes.mnc> [--xfm <xfm>]

DESCRIPTION

lobes_to_volumes.pl computes the volumes (in cubic millimetres) of each labelled brain lobe from a lobe-segmented MINC volume produced by lobe_segment. The volumes are printed to standard output, one label per line.

If a transformation (.xfm) is provided via the --xfm option, the voxel volumes are adjusted according to the Jacobian determinant of the transformation, allowing the output to reflect volumes in a different coordinate space (e.g. native space volumes when the labels are in stereotaxic space).

OPTIONS

--xfm <xfm>

Apply the specified transformation to adjust voxel volumes by its Jacobian determinant. This is useful for computing native-space volumes from labels defined in stereotaxic space.

EXAMPLES

Compute lobe volumes directly from a labelled volume:

lobes_to_volumes.pl lobes.mnc

Compute native-space volumes using a stereotaxic transformation:

lobes_to_volumes.pl lobes.mnc --xfm subject_to_tal.xfm

Save volumes to a file:

lobes_to_volumes.pl lobes.mnc --xfm subject_to_tal.xfm > volumes.txt
