I. Matlab files:
----------------
	1- Learndata1/Testdata1 contains data that was sampled at 360 sample/sec:
		- normal, VCouplet, VTachy, VBigeminy.
		- AIVR (Accelerated IdioVentricular Rhythm) exists only in Testdata1 .

	2- ECGdata2/Testdata2 contains data that was sampled at 250 sample/sec:
		- VFibrillation.

	3- (Learn/Test)info contains:
		- (Learn/Test)classes: 
			- Learn: (normal, VCouplet, VTachy,VBigeminy,VFibrillation).
			- Test:  (normal, VCouplet, VTachy,VBigeminy,AIVR,VFibrillation).

		- No_(Learn/Test)classes: 5/6
		- No_Learnsamples: 	  64 (in each class.)
		- No_TestSamples:  	  32 (in each class.)

II. Text files
--------------
	1- README

	2- filenames contains text file names corresponding to each signal in both 
	   learning and testing samples.
	   A sample file name encodes the record number & at what time:
		ex: "106-1234.txt" is a 3-sec period from record #106 starting at 12:34
