PTEST(1)                          User Manual                         PTEST(1)



NAME
       ptest - Classify sequences using a trained classifier.

SYNOPSIS
       ptest [options] serialized-classifier.txt input.txt

DESCRIPTION
       Read  a trained classifier and a set of sequences and apply the classi-
       fier to each sequence of the set.  A confusion matrix and total classi-
       fication loss is given for the input set.

PARAMETERS
       --confusion-matrix <file>
              Write a confusion matrix for the sequence set to the given file.

       --dump-classifier <file>
              Write a textual description of the serialized classifier.

INPUT FILE FORMAT
       The input file consists of n lines, each containing a  filename  and  a
       class  label, separated by any whitespace character.  The filename cor-
       responds to a sequence file.  If only two classes are  considered,  the
       class  labels  are  "1"  and "-1", for the positive and negative class,
       respectively.  If more classes  are  considered,  the  first  class  is
       labeled "0", and the following classes "1", "2", etc.

       Each  sequence  file  consists  of  p lines, each line representing one
       sequence element.  Each element contains a number  of  items  (positive
       integer numbers), separated by whitespace characters.  The items within
       each element must be ordered and contain no duplicate item.

BUGS
       No bugs known, if you find any, please send a bug report to me. I  will
       try to fix it.
