NAME

mcx ctty - compute the clustering coefficient of a graph

SYNOPSIS

mcx ctty [options] [matrix-file]

mcxctty is not in actual fact a program. This manual page documents the behaviour and options of the mcx program when invoked in mode ctty. The options -h, --apropos, --version, -set, --nop, -progress <num> are accessible in all mcx modes. They are described in the mcx manual page.

mcx ctty [-abc <fname> (specify label input)] [-imx <fname> (specify matrix input)] [-tab <fname> (use tab file)] [--list (list clustering coefficient for all nodes)] [-h (print synopsis, exit)] [--apropos (print synopsis, exit)] [--version (print version, exit)]

DESCRIPTION

mcx ctty computes centrality betweenness for all nodes in a graph, using the between centrality update algorithm from [1].

The input graph/matrix, if specified with the -imx option, has to be in mcl matrix/graph format. You can use label input instead by using the -abc option. Refer to mcxio(5) for a description of these two input formats. By default mcx diameter reads from STDIN and expects matrix format. To specify label input from STDIN use -abc -.

OPTIONS

-abc <fname> (label input)
The file name for input that is in label format.

-imx <fname> (input matrix)
The file name for input. STDIN is assumed if not specified.

-tab <fname> (use tab file)
This option causes the output to be printed with the labels found in the tab file. With -abc this option will, additionally, construct a graph only on the labels found in the tab file. If this option is used in conjunction with -imx the tab domain and the matrix domain are required to be identical.

--list (print result for each node)
Print clustering coefficient for all nodes.
