no consistency between plot and table

[Amir alipour yengejeh]

Hello,

I am using Lefse commands on biobakery. However, my problem is that when I generate histogram plots by Wilcoxon p-value=0.00001 the number of bars for LDA>2 and p=0.00001 is 27, while I back the table and filter data the number is 21 for same boundaries?

I hope somebody could help me?

Sincerely, 

Amir.
