| **-s, –sorting-criteria**\ =\ *C*
| Specify how to sort the connected components by size:

-  p) path mass (total number of path bases) (default)

-  l) graph length (number of node bases)

-  n) number of nodes

-  P) longest path

| **-O, –optimize**
| Compact the node ID space in each connected component.

Threading
---------
