LIPSIA     Brain peeling
vbrainpeel
The program 'vbrainpeel' performs a "brain peeling", i.e. it zeroes-out any non-brain matter from the image.
Usage
Example:

vbrainpeel -in infile.v -out outfile.v

The input into 'vbrainpeel' is an MR-image with isotropic voxels. It is recommended (but not required) that the image has been rotated into Talairach space using the program 'vtal' beforehand.

Brain peeling is performed by using a sequence of image processing operations. These operations can be influenced by the parameters '-d1', '-d2', '-t', '-edge', 'background'.

Parameters of 'vbrainpeel':
