Returns a graph object with vertices that meet certain criteria. By default,
only vertices that meet these criteria for *all* input graphs will be
retained.

1 | ```
make_intersection_brainGraph(..., subgraph, keep.all.vertices = FALSE)
``` |

`...` |
Graph objects or lists of graph objects |

`subgraph` |
Character string specifying an equation (logical condition) for the vertices to subset |

`keep.all.vertices` |
Logical indicating whether to keep all vertices that
meet the criteria in at least 1 input graph. Default: |

If no vertices meet criteria for all input graphs, then an `igraph`

graph object with 0 vertices is returned. If `keep.all.vertices=TRUE`

,
this is essentially performing a *union* of vertex sets that meet the
criteria. In any case, the return graph will have 0 edges.

An `igraph`

graph object
