GA Fuzzy Clustering Description

The GA Fuzzy Clustering application was developed to be a program that uses combination of Genetic Algorithm and C-Means method for clustering of microarray data and distance matrix data. Input file format:: - This program uses a plain text file as input. - All the data items must be separated by tabulators. - No missing values are allowed. Microarray: - First line contains names of all columns. - Each line (beginning with second) must have the gene name (1 column or more) and the expression values for each condition. Distance matrix: - First line contains caption (single word or a string in the 1st position) and names of elements - Each line (beginning with second) must contain name of element (the same, as in the corresponding column) and values of distances between this element and the others. - Matrix is symmetric. - All values are normalized (not greater than 1.0). - Note: similarity matrix is also allowed. Output file format: - Parameters of the algorithm - Distribution of genes in clusters (if membership is > 1/nuberOfClusters) - Membership matrix for all genes - Coordinates of centers of clusters (in the gene expression units)
