calc_topological_indices(ig, ncores = 0)
``` |

`ig` |
vector of igraph objects |

`ncores` |
number of cores used to compute in parallel, if 0 sequential processing is used. |

`Basal:` |
Number of basal especies |

`Omnivory:` |
Number of omnivory species, is the number |

`Links:` |
number of interactions |

`LD:` |
linkage density |

`Connectance:` |
Connectance |

`PathLength:` |
average path length |

`Clustering:` |
clustering coeficient |

`Cannib:` |

`TLmax:` |
maximum trophic level |

`Components:` |
number of weakly connected components |

1 2 3 4 5 6 7 | ```
calc_topological_indices(netData)
# Generate a test network
