Hi Paola,
It all looks fine to me - but maybe I'm not understanding.
You have this in your config file:
```
[data_blocks]
cytb_pos1 = 1 - 303\3;
cytb_pos2 = 2 - 303\3;
cytb_pos3 = 3 - 303\3;
```
and in your best scheme file the best scheme joins all of these together
```
Subset | Best Model | # sites | subset id | Partition names
1 | GTR+I+G | 303 | c5451ff6157270a8d2caeebf094fa94f | cytb_pos1, cytb_pos2, cytb_pos3
```
All three of your partitions are in there, so I'm not quite sure what you think the problem is.
Do let me know if I totally misunderstood though!
