dataset_summary: >-
  AggregatorAdvisor identifies molecules that are known to aggregate or may
  aggregate in biochemical assays based on the chemical similarity to known
  aggregators, and physical properties. In the default affinity range of 100 nM
  to 10 μM, if calculated LogP > 3 and Tc ≥ 85%, the user is informed that this
  compound should be investigated as an aggregator.  If either calculated LogP >
  3 or Tc > 85%, the user is warned that one of these two contributing criteria
  are in effect and that controls should be run.  If neither of these is true,
  this is reported, and the user is counseled that controls are always advised.
  The train and test datasets were created after sanitizing and splitting the
  original dataset in the paper below.

# Aggregator Advisor 
The train and test datasets uploaded to our Hugging Face repository have been sanitized and split from the original dataset, which contains 12645 compounds.
If you want to try these processes with the original dataset, please follow the instructions in the [Processing Script.py](https://huggingface.co/datasets/maomlab/AggregatorAdvisor/blob/main/Preprocessing%20Script.py) file located in the AggregatorAdvisor.
The [raw_data.csv](https://huggingface.co/datasets/maomlab/AggregatorAdvisor/blob/main/raw_data.csv) is the original dataset from the paper, 
and the files in [AggregatorAdvisor](https://huggingface.co/datasets/maomlab/AggregatorAdvisor/tree/main/AggregatorAdvisor) are the sanitized version files that we made.

## Quickstart Usage

### Load a dataset in python
Each subset can be loaded into python using the Huggingface [datasets](https://huggingface.co/docs/datasets/index) library.
First, from the command line install the `datasets` library

    $ pip install datasets

then, from within python load the datasets library

    >>> import datasets
   
and load one of the `AggregatorAdvisor` datasets, e.g.,

    >>> AggregatorAdvisor = datasets.load_dataset("maomlab/AggregatorAdvisor", name = "AggregatorAdvisor")
    Downloading readme: 100%|██████████| 4.70k/4.70k [00:00<00:00, 277kB/s]
    Downloading data: 100%|██████████| 530k/530k [00:00<00:00, 303kB/s]
    Downloading data: 100%|██████████| 2.16M/2.16M [00:00<00:00, 12.1MB/s]
    Generating test split: 100%|██████████| 2529/2529 [00:00<00:00, 29924.07 examples/s]
    Generating train split: 100%|██████████| 10116/10116 [00:00<00:00, 95081.99 examples/s]

and inspecting the loaded dataset

    >>> AggregatorAdvisor
    DatasetDict({
    test: Dataset({
        features: ['new SMILES', 'substance_id', 'aggref_index', 'logP', 'reference'],
        num_rows: 2529
    })
    train: Dataset({
        features: ['new SMILES', 'substance_id', 'aggref_index', 'logP', 'reference'],
        num_rows: 10116
    })
})

### Use a dataset to train a model
One way to use the dataset is through the [MolFlux](https://exscientia.github.io/molflux/) package developed by Exscientia.
First, from the command line, install `MolFlux` library with `catboost` and `rdkit` support

    pip install 'molflux[catboost,rdkit]'

then load, featurize, split, fit, and evaluate the catboost model

    import json
    from datasets import load_dataset
    from molflux.datasets import featurise_dataset
    from molflux.features import load_from_dicts as load_representations_from_dicts
    from molflux.splits import load_from_dict as load_split_from_dict
    from molflux.modelzoo import load_from_dict as load_model_from_dict
    from molflux.metrics import load_suite

Split and evaluate the catboost model
    
    split_dataset = load_dataset('maomlab/AggregatorAdvisor', name = 'AggregatorAdvisor')
    
    split_featurised_dataset = featurise_dataset(
      split_dataset,
      column = "new SMILES",
      representations = load_representations_from_dicts([{"name": "morgan"}, {"name": "maccs_rdkit"}]))

    model = load_model_from_dict({
    "name": "cat_boost_regressor",
    "config": {
        "x_features": ['new SMILES::morgan', 'new SMILES::maccs_rdkit'],
        "y_features": ['logP']}})

    model.train(split_featurised_dataset["train"])
    
    preds = model.predict(split_featurised_dataset["test"])

    regression_suite = load_suite("regression")

    scores = regression_suite.compute(
        references=split_featurised_dataset["test"]['logP'],
        predictions=preds["cat_boost_regressor::logP"])    

### Data splits
Here we have used the `Realistic Split` method described in [(Martin et al., 2018)](https://doi.org/10.1021/acs.jcim.7b00166) to split the AggregatorAdvisor dataset.
