# Blood-Brain Barrier Database

+
## Quickstart Usage
|
89 |
+
|
90 |
+
### Load a dataset in python
|
91 |
+
Each subset can be loaded into python using the Huggingface [datasets](https://huggingface.co/docs/datasets/index) library.
|
92 |
+
First, from the command line install the `datasets` library
|
93 |
+
|
94 |
+
$ pip install datasets
|
95 |
+
|
96 |
+
then, from within python load the datasets library
|
97 |
+
|
98 |
+
>>> import datasets
|
99 |
+
|
100 |
+
and load one of the `B3DB` datasets, e.g.,
|
101 |
+
|
102 |
+
|
103 |
+
and inspecting the loaded dataset
|
104 |
+
|
105 |
+
|
106 |
+
### Use a dataset to train a model
|
107 |
+
One way to use the dataset is through the [MolFlux](https://exscientia.github.io/molflux/) package developed by Exscientia.
|
108 |
+
First, from the command line, install `MolFlux` library with `catboost` and `rdkit` support
|
109 |
+
|
110 |
+
pip install 'molflux[catboost,rdkit]'
|
111 |
+
|
112 |
+
then load, featurize, split, fit, and evaluate the a catboost model
|
113 |
+
|
114 |
+
import json
|
115 |
+
from datasets import load_dataset
|
116 |

from molflux.splits import load_from_dict as load_split_from_dict
|
119 |
+
from molflux.modelzoo import load_from_dict as load_model_from_dict
|
120 |
+
from molflux.metrics import load_suite
|
121 |
+
|
122 |
+

|
123 |
+
|
124 |

|
125 |
+
split_dataset,
|
126 |
+
column = "SMILES",
|
127 |
+
representations = load_representations_from_dicts([{"name": "morgan"}, {"name": "maccs_rdkit"}]))
|
128 |
+
|
129 |
+
model = load_model_from_dict({
|
130 |
+
"name": "cat_boost_classifier",
|
131 |
+
"config": {
|
132 |
+
"x_features": ['SMILES::morgan', 'SMILES::maccs_rdkit'],
|
133 |
+
"y_features": ['BBB+/BBB-']}})
|
134 |
+
|
135 |
+
model.train(split_featurised_dataset["train"])
|
136 |
+
preds = model.predict(split_featurised_dataset["test"])
|
137 |
+
|
138 |
+
classification_suite = load_suite("classification")
|
139 |
+
|
140 |
+
scores = classification_suite.compute(
|
141 |
+
references=split_featurised_dataset["test"]['BBB+/BBB-'],
|
142 |
+
predictions=preds["cat_boost_classifier::BBB+/BBB-"])
|
143 |
+
|
144 |
+
>>> B3DB_classification = datasets.load_dataset("maomlab/B3DB", name = "B3DB_classification")

|
150 |
+
|
151 |
+
### Features of B3DB
|
152 |
+
|
153 |
+
|
154 |
+
### Data splits
|
155 |
+
The original B3DB dataset does not define splits, so here we have used the `Realistic Split` method
|
156 |
+
described in [(Martin et al., 2018)](https://doi.org/10.1021/acs.jcim.7b00166).
