pipeline_pve.pl
partial volume estimation pipeline
pipeline_pve.pl <t1_tal> <classified> <output_base>
DESCRIPTION
pipeline_pve.pl performs partial volume estimation (PVE) on a classified brain volume. While tissue classification assigns each voxel to a single tissue class, PVE estimates the fractional content of white matter, grey matter, and cerebrospinal fluid within each voxel. This is particularly important at tissue boundaries where a single voxel may contain a mixture of tissue types.
The script takes a T1-weighted volume in Talairach space and its corresponding discrete tissue classification as input, and produces partial volume maps with the given output base name. The output files typically include separate volumes for the fractional content of each tissue class.
OPTIONS
-verbose- Print progress information during processing.
-clobber- Overwrite output files if they already exist.
EXAMPLES
Compute partial volume estimates:
pipeline_pve.pl t1_tal.mnc classified.mnc pve_output
Compute with verbose output:
pipeline_pve.pl t1_tal.mnc classified.mnc pve_output -verbose
