 If users want to fix model parameters, append the model name with a curly bracket `{`, followed by the comma-separated rate parameters, and a closing curly bracket `}`. For example, `GTR{1.0,2.0,1.5,3.7,2.8}` specifies 6 substitution rates A-C=1.0, A-G=2.0, A-T=1.5, C-G=3.7, C-T=2.8 and G-T=1.0. 
 
-Another example is for model `TIM2` that has the 6-digit code `010232`. Thus, `TIM2{4.39,5.30,12.1}` means that A-C=A-T=4.39 (coded `1`), A-G=5.30 (coded `2`), C-T=12.1 (coded `3`) and C-G=G-T=1.0 (coded `0`). This is, in turn, equivalent to specifying `GTR{4.39,5.30,4.39,1.0,12.1}`.
