icikt 1.1.3

Python tool to calculate the KendallTau correlation coefficients.

Description

The icikt package provides a Python tool to calculate an information-content-informed Kendall Tau correlation coefficient between arrays, while also handling missing values or values which need to be removed.

Full API documentation, user guide, and tutorial can be found on readthedocs

Installation

The icikt package runs under Python 3.4+. Use pip to install. Starting with Python 3.4, pip is included by default.

Install on Linux, Mac OS X

python3 -m pip install icikt

Install on Windows

py -3 -m pip install icikt

Upgrade on Linux, Mac OS X

python3 -m pip install icikt --upgrade

Upgrade on Windows

py -3 -m pip install icikt --upgrade

GitHub Package installation

Make sure you have git installed:

git clone https://github.com/MoseleyBioinformaticsLab/pythonICIKendallTau.git

Dependencies

icikt requires the following Python libraries:

• numpy and scipy for mathmatical calculations.

• docopt for a command line interface.

• Cython for optimized performance.

To install dependencies manually:

pip3 install numpy
pip3 install scipy
pip3 install docopt
pip3 install cython

Basic usage

To use the icikt package, input a 2d array with n columns each representing an array of data for a variable. The iciktArray will return two n x n 2d arrays for correlations and p-values. Each element will correspond to the result of a combination of two columns in the input array. iciktArray can also be called from the command-line interface given the file path for the data along with several optional parameters(more in docs/tutorial).

Running through command line :

icikt iciktArray /path/to/file.tsv --data-format=tsv --replace=None

Running through python script :

import numpy as np
import icikt

dataArray = np.genfromtxt('/path/to/file.tsv', delimiter="\t")
# or with random values
dataArray = numpy.random.randn(100, 2)

# running just 2 arrays with icikt
corr, pVal, tMax = icikt.icikt(dataArray[:,0], dataArray[:,1])

# running all combinations with iciktArray
scaled, corrRaw, pVals, tauMax = icikt.iciktArray(dataArray)
