amova design file

mothur bugs

Dear PD.schloss
Thanks for your mothur which help me analyze my data, but I have a problem when I performed amova analysis. I tried to use different letters represent different groups,but I only got the results together, rather than the result of the comparison in pairs.
This is my result:
WT-WW-WX-WXL-WXS Among Within Total
SS 0.342839 5.71399 6.05683
df 4 78 82
MS 0.0857097 0.0732563

Fs: 1.17
p-value: 0.211

My design file like this:

Is it a problem with my design file? Can you help me fix it?

Thanks,

Hi,

We only provide the top-level comparison of all groups when your P-value is greater than 0.05. Your p-value is 0.211, which indicates that none of the five groups is significantly different from the others. Because of this, it does not make sense and is in fact risky, to then do the pairwise comparisons. There is no significant difference between your five groups (P=0.211).
