Programs (*.pyc) are compiled using Python 2.4.

Run PYC files. Please follow the popup questions and input the corresponing filenames for a successful prediction.

Building upcast sets of triples (triangles, lines and triples) of characteristic categories

  • Use triple-wise protein interactions and protein annotation

  • Include triples (triples, triangles, lines) of characteristic categories

  • Integrate multiple characteristics

Query protein pairs

  • A list of protein pairs to be predicted.

  • As an eligible protein pair (predictable), the characteristics, i.e. structure and/or function, of the two flanking proteins are known and there exists at least one common interacting protein neighbours. For the common interacting proteins, the characteristics are also known.

Method

The triangle rate score


Example -- Predicting 5 selected protein pairs

Sample datasets

Convert classifications from txt file to Python shelve PYC file

Output -- structural classification (shelve), functional classification (shelve)

Construct upcast set of triples (triangles and lines) of characteristic categoriesPYC file

Output -- use both structure and function classifcations (triangles, lines)

Prediction

The triangle rate score (PYC file, result)


Our upcast sets

S.cerevisiae (triangles and lines), Eukaryotes (triangles and lines, Prokaryotes (triangles and lines), All interactions (triangles and lines)
