| avg_probe_exp | Function to produce a matrix containing the average expression of each gene probe within each sample cluster. | 
| cluster_analysis | Function to perform Kmeans or Hierarchical clustering analysis of the selected gene probe expression data. | 
| input_file | Function to read-in the gene expression file and assign gene probe names as the rownames. | 
| nor.min.max | Function to normalize data to bring values into alignment. This function uses feature scaling to normalize values in a dataset between 0 and 1. | 
| number_clusters | Function to determine the number of clusters to be used to cluster gene probes and samples. | 
| number_probes | Function to determine the number of gene probes to select for in the gene feature selection process. | 
| probe_ranking | Function to select for genes using one of the available gene probe ranking options. | 
| surv_analysis | Function to produce Kaplan-Meier Survival Plots of selected gene expression data. | 
| WriteMatrixToFile | Function to write a data matrix to a text file. |
