Hello everyone!

I have 48 samples that divided to two groups ( MOL = 26 , PIC = 22 ). As I expected they are significant.
In the first plot (Distances to MOL) it is written that "MOL (n = 325) and PIC (n = 572)". What are these "n" here?

Best,
Armin

Hi @ari_sh70 ,

ari_sh70:

What are these “n” here?

The Ns in this plot are not number of samples, but rather number of pairwise comparisons. See an explanation here:

Hey @saatkinson ,
Thanks! I was able to re-run your command to look at the results.
For the figures, the n doesn’t represent the number of samples, but rather the number of pairwise comparisons that make up the distribution for the metric that the box-plot represents. For example, your 2920X_Control vs 2920X_Control has a sample-size of 7, and so the number of possible pairwise comparisons would be \frac{7 * (7-1)}{2} = 21 which matches what we see in the second figure. To state it a…
Judging from your PCoA plot here, it looks like the sample sizes are MOL=26, PIC=22:
