Benchmarking Pipeline for the Prediction of Protein-Protein Interactions

How this benchmarking pipeline has been built, and how to use it, is detailed in our preprint here (please cite it if you find this work useful!).

A minimal example is available here, and the list of requirements there.

How to use the gold standard

All the data files are in data, most of them are available as csv (sep='|') and pickled pandas DataFrames (sometimes the csv file may be missing due to file size constraints on GitHub).

The gold standard, without pre-processed features, can be loaded using:

goldStandard = pd.read_csv(
    os.path.join('data', 'benchmarkingGS_v1-0.csv'),
    sep='|'
)

Or with the pre-processed features:

goldStandard_with_featuresSeq = pd.read_pickle(
    os.path.join('data', 'benchmarkingGS_v1-0_similarityMeasure_sequence_v3-1.pkl')
)

• UniProtIDs are used for both proteins A and B.
• isInteraction is the ground truth from the IntAct database (1 = interacting proteins, 0 = non-interacting proteins).
• trainTest is the split between training set (train), first testing set T1 (test1) and second testing set T2 (test2).
• Pre-processed features are explained in the manuscript.

Training and evaluation can then be done normally. The code from the preprint is in the Training section.
