USAGE

.OPERATION: CL HD

.CUTOFF THRESHOLD % (0-100): 20
[Enter the scale value at which the dendrogram will be cut/truncated. Classes with indices below the threshold will be merged. If the threshold is zero no merger is done and the classes retain their original numbers. For threshold > 0 classes are renumbered.]

.DENDOGRAM DOCUMENT FILE: DEND_CL
[Enter name of the untruncated dendrogram document file containing classification tree produced by 'CL CLA' or 'CL HC').]

.DOCUMENT FILE: DEND_NUM
[Enter the document file name which will contain number of objects belonging to each class.]

NOTES

1. To get selection doc files corresponding to a given "cutting" use command 'CL HE'.
