Amino Acid Content Statistical Test

I would like to compare the amino acid and the codon usage content between two organisms. What statistical test would be appropriate for this purpose? And what are the inputs needed?

statistics amino-acids

Could be a little more specific? What are you looking for? Just that two organisms have a diference in codon content?

I recommend that you study the work of Jean Lobry, who has done a lot of work in this area.

Search PubMed for "Lobry JR[AU]" or see his partial list of publications.

He has also written an R package called seqinR which contains many methods for statistical analysis of sequences, including composition. Read the documentation, in particular chapter 9 on multivariate analysis.
