Microarray Data Analysis

  • Each time point had 4 replicates.
  • The dollar sign is important because the formulas must include the same average and same standard deviation when they are pasted down the entire column. WIthout the use of the dollar sign the excel would continue to down the column and use the wrong cells in the formula.

  • Keeping the "Pval" filter at p < 0.05, filter the "AvgLogFC" column to show all genes with an average log fold change greater than zero. How many meet these two criteria? (time = t60)
    • 786
  • Keeping the "Pval" filter at p < 0.05, filter the "AvgLogFC" column to show all genes with an average log fold change less than zero. How many meet these two criteria? (time = t60)
    • 824
  • Keeping the "Pval" filter at p < 0.05, How many have an average log fold change of > 0.25 and p < 0.05? (time = t60)
    • 755
  • How many have an average log fold change of < -0.25 and p < 0.05? (time = t60)
    • 763
