               }
train_smiles_df = pd.DataFrame(data=train_smiles)

test_smile = train_smiles
test_smile_df = pd.DataFrame(test_smile)

#Train, Test, feature_sequences, feature_to_token_map = fe_1mol.oneMolFeatureExtraction(trainSMILES=train_smiles_df, testSMILES=train_smiles_df,ngram_list=[1,2,3,4,5,6,7,8])
Train, Test, feature_sequences, feature_to_token_map = fe_1mol.oneMolFeatureExtraction(trainSMILES=train_smiles_df, testSMILES=None,ngram_list=[1,2,3,4,5,6,7,8])

Note:

The input to the method oneMolFeatureExtraction() must be a pandas DataFrame with atleats two columns:

• DRUG_NAME
• SMILES

The column name should be in capital letters.
