# clmmeet(1)

clm\_meet - compute the intersection of a set of clusterings.

clmmeet is not in actual fact a program. This manual page documents the behaviour and options of the clm program when invoked in mode *meet*. The options **-h**, **--apropos**, **--version**, **-set**, **--nop** are accessible in all **clm** modes. They are described in the **clm** manual page.

**clm meet** **\[-o** fname (*output file name*)**\]** **\[-h** (*print synopsis, exit*)**\]** **\[--apropos** (*print synopsis, exit*)**\]** **\[--version** (*print version, exit*)**\]** \<file name\>+

**clm meet** computes the intersection of a set of clusterings, that is, the largest clustering that is a subclustering of all the clusterings in the set. It stores the intersection (or meet) in the argument to the **-o** flag, which must be the first option given. All remaining arguments are interpreted as names of files containing clusterings in mcl format (see **[mcxio(5)](/mcxio/5.md)**), which must all pertain to a set of the same cardinality.

This utility can be useful in measuring (in conjunction with **clm dist**) the consistency of a set of clusterings at different levels of granularity - if the meet of all those clusterings is close to being a subclustering of each of them, consistency is good. See **clm dist** for an example.
