Attached is half of the table in a brf file...you would need to split the table into two parts (which requires a TN) and the TN included is just a description of what's needed...not the actual TN to include. It's a suggestion...no rules about this! As for the circular graphic, I wonder if you could draw it with keys - or you could explain that it is a circle and list the information in each quarter...
first quarter G (cell 1) U (cell 3) U (cell 5) Valine (cell 7) and so on
Again, just a suggestion 🙂
