TPM3uf+G in xml file

[Cat reeb]

Hye,

I am wondering to implement the model TPM3uf+G in Beauti. Is it possible to get it directly through beauti parameters ? Or do we need to modify the xml file, and in this case how to manage it ? I get the http://beast.bio.ed.ac.uk/Substitution-model-code but the TPM3uf+G model is not implemented in, and the principe  of modification  of the xml file is not clear for me, even if I understand the blocks to modify (gtr model, operators, file log etc...)

In jModeltest manual, the parameters given are

TPM3uf 5 unequal AC=CG;AT=GT;AG=CT 

how to translate that in the substitution model in xml ?

Thanks a lot for help
