This software implements the ARoSi algorithm for segmentation of brain region from T1-weighted brain MR volume, proposed in the following paper:      

	Shaswati Roy and Pradipta Maji, An Accurate and Robust Skull Stripping Method for 3-D Magnetic Resonance Brain Images, Magnetic Resonance Imaging, pp. 1--14, 2018


Quick Start
===========

Before using the Accurate and Robust Skull Stripping (ARoSi) algorithm make sure the directory contains the input volume (in NIFTI .nii format).

This algorithm takes two options:
	a) -f: The input filename for T1-weighted brain MR volume (in .nii format) and
	b) -o: The output filename for brain mask (in .nii format).


Installation
=============

On Unix systems with 64-bit, read-write-execute permission is to be given to the arosi.out by using the command "chmod 777 arosi.out".


Example
========

$ chmod 777 arosi.out
$./arosi.out -f IBSR_01_ana.nii -o IBSR_01_ana_brain_mask.nii
