This tool can be used for academic and research purposes. To use this tool the following stepsshould be taken: 1. copy the gene_term.txt file from the datasets folder to d:\\ If you are using yeast datasets copy the GeneTermTree\yeast\gene_term.txt file to d:\\ If you are using human datasets copy the GeneTermTree\human\gene_term.txt file to d:\\ 2. The data provided herewith are formatted appropriately. 3. The tool can be executed by double clicking kmeans1.exe. The datasets should be inputted accordingly. User can set thresholds as per their wish. If using Pearson simTH = 70 means 0.75. no of conditions is the total conditions in the dataset. PrintResult button will write the cluster results in a file clusterResult.txt and save it in d:\ 4. The button C will show the cluster profiles in another window. 5.
