NAME
     prword -- generate whole-word data sets  for  PRW  workbench
     from SFS files

SYNOPSIS
     first usage:
     prword (-i item) (-s start) (-e end)  (-n)  (-L  labelrange)
     (-p vectorlength) (-f labelname) (-d dbrange) (-0) -l label-
     value patbase file
     subsequently:
     prword (-i item) (-s start) (-e end) (-d  dbrange)  (-0)  -l
     labelvalue patbase file

DESCRIPTION
     prdat generates the labels and vectors  files  used  by  the
     Pattern  Recognition workbench from SFS files for whole-word
     pattern vectors.  In the default mode, it will input a  com-
     bination  of CO and TR items from the file and a label value
     on the command line to add a  single  pattern  vector  to  a
     named   labels   file   (patbase.lab)   and   vectors   file
     (patbase.vec).  The first run for a new data set  should  be
     labelled  with the '-f' switch.  If you wish the patterns to
     be padded to a certain vector  length,  use  the  Subsequent
     runs should match the first in construction.

     Coefficient scaling is linear mapping down to  0..1  of  the
     top  dB  range  of  the  data (default 50dB but switchable).
     Tracks are not scaled.  An option maps  negative  values  to
     zero.

     Options:

     -I         Identify the program name and version.

     -iitem     Select input item number. Select  combination  of
                CO and TR to build pattern vector.

     -sstart    Select start time (in seconds). Default 0.

     -eend      Select end time (in seconds).  Default:  earliest
                end of an input item.

     -n         New data set, delete any existing pattern  vector
                files of same name.

the length
     Specify the length of the pattern vector to be created.  This  is
                in floats not frames, and should be a multiple of
                the framesize.  Pattern shorter than  the  vector
                length  will be centered and padded using repeti-
                tions of the first  and  last  frames.   Default:
                variable length patterns.

     -ffeatname Provide a name for the vector label to  store  in
                the  labels file.  Only needed for first data set
                in pattern vector labels file.

     -ddbrange  Compress top 'dbrange' of coefficient energies to
                range 0..1.  Default 50.

     -0         Set all negative input values in  pattern  vector
                to zero.  Default: leave negative values alone.

FILES
     <patbase>.lab       patern labels

     <patbase>.vec       pattern vectors

     <patbase>.inf       pattern file information
