Greetings,

Students in our bioinformatics course are working on individual projects and one of the pairs are trying to determine codon usage preference between the host bacteria and some phages that encode for 16-20 tRNAs. We tried to using COUSIN (COdon Usage Similarity INdex) but that is not working as we get an error message for the output. Does anyone know of other programs that can determine codon usage preference that do not require coding knowledge?

Thank you,

Arturo
