1) Download de package

Go to the page::

	https://pypi.python.org/pypi/waipy/

Download waipy-version.tar.gz

2) Unpacked in you download dir::

	tar -vzxf waipy-version.tar.gz
3) Enter into the directory:: 

	cd waipy-version
4) Install package::

	python setup.py install
5) Open ipython:: 

	ipython
	import waipy
	# loading data for test
	data,time = waipy.load_txt('sst_nino3.dat',0.25,1871)
	# normalizing time series
	data_norm = waipy.normalize(data)
	# calculating continuos wavelet transform using Morlet wavelet
	result = waipy.cwt(data_norm,0.25,1,0.25,2*0.25,7/0.25,0.72,6,'Morlet')
	# ploting the result - impath: 'Users/you/figures/'
	waipy.wavelet_plot('SST_NINO3',time,data,0.03125,result,impath)


	CROSS ANALYSIS
	cross_power, coherence = waipy.cross_wavelet(result['wave'],result['wave'])
	waipy.plot_cross(cross_power,time,result)
	waipy.plot_cohere(coherence,time,result)
