-### likelihood
-Phenopy can be used to predict the likelihood of a molecular diagnosis given an input set of HPO phenotypes. This functionality takes the same input records file as the `score` functionality. The likelhood command outputs a probability of finding a moleular diagnosis using a model trained on 46,674 probands primarily with the majority of them having a neurodevelopmental delay phenotype.
-
-To score a list of records with phenotypes:
-
-```bash
-phenopy likelihood tests/data/test.score-long.txt
-```
-
-If the `output_file` argument is not set, this command writes a file, `phenopy.likelihood_moldx.txt` to your current working directory.
-Look at the predicted probabilities for the first five records:
-
-```bash
-$ head -5 phenopy.likelihood_moldx.txt
-```
-
-The columns are `record_id` and `probability_of_molecular_diagnosis`:

-```bash

 ### miscellaneous
 
 The library can be used to prune parent phenotypes from the `phenotype.hpoa` and store pruned annotations as a file
