vol.mask.from.segmentation

Extract subset from a volume by value, set all other voxel values to <code>NA</code>. Typically used to extract a brain structure (like corpus callosum) from a volume segmentation (like the <code>mri/aseg.mgz</code> file of a subject). You should consider passing the volume and the include values as integers.

Provides high-level access to neuroimaging data from standard software packages like 'FreeSurfer' <http://freesurfer.net/> on the level of subjects and groups. Load morphometry data, surfaces and brain parcellations based on atlases. Mask data using labels, load data for specific atlas regions only, and visualize data and statistical results directly in 'R'.
