WebSep 11, 2024 · Usually, if overall p-value is high, no need for pairwise comparisons since it is an indicator that there is no significant variation among tested groups. If overall p-value <= 0.05 or a little bit higher, but still close enough you can report q-values from pairwise tests. PS. For only two groups, you can report "overall" p-value.

WebIntroduction. Now, we will discuss in more detail how to assess population genetic structure from sequence data. Assuming that you have a priori information about how the individuals are grouped in subpopulations, one can do the following analyses: 1) quantify pairwise subpopulation structure and their significance, 2) test for hierarchical structure among … WebImporting from other programs. You can see that the two main components that you need to run the diversity analyses is a frequency table and representative sequences. This means we should be able to import results from other other programs, such as OBITools, into Qiime2 to run the statistics. We will try this using the table and ZOTUs from the ...
