CLUSEXT: Extract Clustering Information

Last updated 19 Nov 97

This program extracts cluster solution information and writes it to a text file. The user can then write or run other software to use this data.

Program Invocation

The specific syntax for program invocation varies between operating systems. This document diplays the code for the AIX version.


@codap clusext <opt> <ssss> <CSf> <CI>

ssss:   The study number
opt:    None currently supported
CSf:    Input Cluster Solution file
CI:     Output card image file 

CLUSEXT Control Card


<pseq>

pseq:   cc 01-06  The input presentation sequence.

Example

@codap clusext - ssss cs100
ps0001 

This example extracts the clustering information associated with presentation sequence PS0001 for file cs100.
