Specify type of graphing to do: Graphing: (Graphing Help Page) Produce: Expression Histogram Scatterplot of Expression vs. Pack-Years for genes: (Separate multiple AFFX IDs with commas. Maximum of 10) Produce a: Sample vs. Sample Scatterplot For Sample: vs. Sample: (This will produce a scatter plot plotting the expression values for all genes in one sample against the expression values for the same gene in the second sample) To get a list of ALL Samples, Click Here Clustering: Produce dendogram by hierarchical clustering of: ALL Microarray Samples ONLY Never Smoker Samples ONLY Current Smoker Samples ONLY Former Smoker Samples Using the following clustering method: Average Median Complete Single Ward Centroid Mcquitty Using the following distance metric: Pearson Correlation Euclidean Maximum Manhattan Canberra Select genes by the following variability parameter: Using the: genes that have the largest difference between Max and Min expression values Using the: genes that have the highest Max/Min Ratio Using genes with a Max/Min Expression Ratio greater than Using genes with a Max/Min Expression Difference greater than Using the: genes that have the largest Standard Deviation of expression values Using genes with a Standard Deviation of expression values greater than Using the: genes that have the largest Standard Deviation to Mean Expression ratios Using genes with a Standard Deviation to Mean Expression ratio greater than Using genes from a User-specified file: (Gene file should be in tab-delimited format with first column containing gene's Affymetrix ID) Using ALL Filtered Genes (Please note Clustering may take a few minutes to run)
