Now I use command to run it like this
```
mxram 10240;
nstates DNA ;
nstates NOGAPS ;
procedure name.tnt ;
log tnt.log ;
hold 1000 ;
mult=replic 10 tbr;
bbreak=tbr ;
majority * ;
taxname= ;
export - trees.nex ;
ttags = ;
resample replications 1000 ;
length * ;
export - bt.nex ;
stats.run;
quit;
```
and all things should be in bt.nex, but it seems like this
How can I let it with branch length, like this
