Procedure
[[Media:Leng_Tai_Yeast_dataset.txt | Dataset containing these calculated columns]]
 * We downloaded the data set from our paper and calculated the following values:
 * The average intensity value for the three samples of 12C Carbon-limiting, 30C Carbon-limiting, 12C Nitrogen-limiting and 30C Nitrogen-limiting
 * Using these averages we calculated two ratios: (12C Carbon Limiting Average/ 30C Carbon limiting average) and (12C Nitrogen-limiting Avg./ 30C Nitrogen-limiting Avg.)
 * We took the log2 of the resulting ratio
 * Finally, ran a TTEST between the 12C and 30C data for both Carbon-limiting cultures and Nitrogen-limiting cultures


 * Sanity Check: We used an Excel function to find the number of genes that were significantly different according to our ttest:
 * For C-limiting data: 2232 of 9336 were significant
 * For N-limiting data: 2333 of 9336 were significant
 * For Both: 942 of 9336 significant
