  NAME
      clm vol - compute volatile nodes from a set of clusterings

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

  SYNOPSIS
      clm vol [-fraction num (nff factor)] [-o fname (output file)] <cl file>+

  DESCRIPTION
      clm vol computes a score for each node, which at a minimum is equal to one.  The output is in the form of a matrix containing a single  col-
      umn.  The  score	correlates with what is deemed to be volatile behaviour. For all pairs of clusterings the set of all intersections is com-
      puted, and these are considered in turn.	An intersection is deemed to be volatile if the size of the intersection is  less  than  half  the
      size  of	the  smallest of the two clusters. In that case, for each node in the intersection its volatility score is incremented by one over
      the size of the intersection.  The size comparison can be made more stringent by increasing the -fraction <frac> option, which is by default
      set  to 0.5.  Volatility occurs if the size of the intersection is less than <frac> times the size of the smallest cluster. If the -fraction
      value is increased all the way up to 1.0, the implication is that an intersection is considered volatile unless one  of  the  two  clusteres
      considered is a subset of the other.
