volume_object_evaluate

evaluate volume values at surface object vertex positions

volume_object_evaluate [options] volume.mnc object.obj output.txt

DESCRIPTION

volume_object_evaluate samples a MINC volume at each vertex position of a BIC object file and writes the interpolated values to a text file. This is useful for extracting intensity profiles or statistical measurements along a surface.

The interpolation method can be selected using command-line options.

OPTIONS

-linear

Use trilinear interpolation (default).

-nearest_neighbour

Use nearest-neighbour interpolation (no smoothing).

-cubic

Use tricubic interpolation.

-rgb

Convert RGB colour values to a colour flag in the output.

EXAMPLES
