Hi,

Can you help me to analyze my RT-PCR data. I've the CT for all my samples and I've compute the dCT. I've four groups of samples ( one group per condition) and I want to perform ANOVA. How can I do that ? in R ?

Here's a example of my dCT matrix

		ctrl1  ctrl2  ctrl3	 A1	 A2	 A3	 B1	 B2	 B3
gene1   7.307  0.237  0.611  9.640  8.705  8.870  7.307  0.611  0.237
gene2   9.061 10.111 11.016 12.025 11.482 10.982  9.061 11.016 10.111
gene3   7.903 12.048 11.911 10.796 10.931 10.648  7.903 11.911 12.048
gene4  11.731 17.809 15.951 19.682 16.964 14.036 11.731 15.951 17.809

I read that the Wilcoxon test is better than the t-test for this kind of data . Is it true ?
