Kristoffer Chin: Week 12

Entry

Normalize Log Ratios

• The original data sheet did not contain the correct amount of names. We had too look at array express and the different excel sheets to find the correct names

• After matching the names, the data from each of the different microarray subject was averaged using the excel formulas.
• The standard deviation was then found on the data as well
• New columns are then made with the same name of the subject along with scaled centered and is given data using the excel formulas

Statistical Analysis of Ratios

• The LOG average was found between TC and AT. These 2 subjects were averaged out and a .txt and xls. was made for GenMAPP and to refer to.

Sanity Check

• 1711 genes were found to be <.05
• 326 genes were found to be <.01
• 34 genes were found to be <.001
• 0 genes were found to be <.0001

• 549 genes that are greater than 0 in Log Avg
• 1162 genes that are less than 0 in the Log Avg
• 1162 genes that are greater that 0.25 or less than 0.25 in the Log Avg.
