 Bacformer can be applied to a wide range of tasks, including: strain clustering, essential genes prediction, operon identification,
-ppi prediction, protein function prediction and more. We provide [model checkpoints]() for pretrained models as well as Bacformer
+ppi prediction, protein function prediction and more. We provide model checkpoints for pretrained models as well as Bacformer
 finetuned for various tasks. We also provide tutorials and make Bacformer available via [HuggingFace](https://huggingface.co/macwiatrak).
