README file for parallelized Gaussian Mean Change Point Detection

Contact (unless otherwise noted):
(C) Nancy Song, Princeton University

Overview: this program executes a parallel version of change point detection
of changes in the Gaussian mean. Note that for fluorescence spectroscopy,
input are the intensities at each time point, not photon counts.

Requirements: GNU C Library 2.12.2+, OpenMPI 1.4.2+

(1)	Build Parallel-GM program using the makefile
(2)	Run Parallel-GM using the following arguments: filename, alpha, beta
	(a) alpha is the Type-I error
	(b) beta is the confidence region. Only accepts values from {0.69, 0.90, 0.95, 0.99}
(3)	Output is a file with the name of the file appended with .cp that has the time index of the 
	change point detected and the left and right confidence intervals

Example:	The following runs Gaussian mean change point detection on the file file1 with two processes
		and a Type-I error of 0.05 and a confidence interval of 0.95

		Type into command terminal:
		mpirun -np 2 Parallel-GM filename 0.05 0.95

		Output file would be file1.cp
		Sample from file1.cp:	
		99 97 104

		This indicates that a change point was found at the 99th time step. 
		Confidence region is from index 97 to 104
