#### Verifying Index Contractions

If you are unsure about how indices are contracted you can check the output of the function `MakeIndexStructure` which is internally used. Example after loading the THDM-II model:

If one is unsure about how indices are contracted you can check the output of the function `MakeIndexStructure` which is internally used. Example after loading the THDM-II model:

In[1]: MakeIndexStructure[{H2, u, q}]

Out[1]: Delta[col2, col3] epsTensor[lef1, lef3]

In case of a supersymmetric model one can view the contrations of all superfields in the superpotential using:
