[EMBOSS] question on 'codcmp'

[Makedonka Dautova]

Hi,

I have a question regarding the output of codcmp (Codon usage table
comparison) and was hopping that you can help me.

After running the program we received the following output file:

---------------------------------------------------------------------------
# CODCMP codon usage table comparison
# anc_can.FULLSPECIES.cuspoutput vs anc_cey.FULLSPECIES.cuspoutput

Sum Squared Difference = 0.036
Mean Squared Difference = 0.001
Root Mean Squared Difference = 0.024
Sum Difference         = 1.038
Mean Difference         = 0.016
Codons not appearing   = 0
---------------------------------------------------------------------------

How do I interpret this? How do I know if the difference is statistically
significant or not?

Thank you in advance,
Makedonka Mitreva.
