Usage: 3dSharpen [options] dataset
Applies a simple 3D sharpening filter to the POSITIVE values
in the #0 volume of the input dataset, and writes out a new
dataset.
Only operates on positive valued voxels in the dataset.
Non-positive values will not be altered.
Options:
--------
-phi fff = Sharpening factor, between 0.1 and 0.9 (inclusive).
Larger means more sharpening. Default is 0.4.
-input dataset = An option to input the dataset anywhere,
not just at the end of the command line.
-prefix pref = Select the name of the output dataset
(it will be in floating point format).
* A quick hack for experimental purposes.
* e.g., Cleaning up the results of brain template construction.
