Hi

Importing the following table as csv, (Import CSV / Class Count / check taxonomy)

taxa pop1 pop2 pop3 pop4 pop5

Nemadoras humeralis 10 50 10 10 10

Schizodon fasciatus 0 0 0 0 10

then showing heatmap with Z-score

I could not find how these values have been computed by megan.

A manually calculation using the formula below does not allow to find the same result.

z = x – μ / σ

thanks

best regards

Cédric
