Data storage and manipulation tools used by GALE. This package contain two different tools. The first one are the ones that deal with data storage. This distribution provides object for reading data in arff format. This self-contained format describes both the data and the available instances. An arff file contains a header (meta-data) and the trailer of the defined instances. For instance:

%%%
%%% Header
%%%
@relation Iris

@attribute sepallength REAL
@attribute sepalwidth REAL
@attribute petallength REAL
@attribute petalwidth REAL
@attribute class {Iris-setosa,Iris-versicolor,Iris-virginica}

4.9,3.0,1.4,0.2,Iris-setosa
4.7,3.2,1.3,0.2,Iris-setosa

For more information please see the WEKA software package at http://www.cs.waikato.ac.nz/ml/weka/. The second set of tools are the ones that build the stratified k-fold cross-validation sets. GALE can be only used for building these sets without running the evolutionary process (-s flag.)
