funtbl: extract a table from Funtools ASCII output

NAME

funtbl - extract a table from Funtools ASCII output

SYNOPSIS

funtable [-c cols] [-h] [-n table] [-p prog] [-s sep] <iname>

DESCRIPTION

[NB: This program has been deprecated in favor of the ASCII text processing support in funtools. You can now perform fundisp on funtools ASCII output files (specifying the table using bracket notation) to extract tables and columns.]

The funtbl script extracts a specified table (without the header and comments) from a funtools ASCII output file and writes the result to the standard output. The first non-switch argument is the ASCII input file name (i.e. the saved output from funcnts, fundisp, funhist, etc.). If no filename is specified, stdin is read. The -n switch specifies which table (starting from 1) to extract. The default is to extract the first table. The -c switch is a space-delimited list of column numbers to output, e.g. -c ``1 3 5'' will extract the first three odd-numbered columns. The default is to extract all columns. The -s switch specifies the separator string to put between columns. The default is a single space. The -h switch specifies that column names should be added in a header line before the data is output. Without the switch, no header is prepended. The -p program switch allows you to specify an awk-like program to run instead of the default (which is host-specific and is determined at build time). The -T switch will output the data in rdb format (i.e., with a 2-row header of column names and dashes, and with data columns separated by tabs). The -help switch will print out a message describing program usage.

For example, consider the output from the following funcnts command:

  [sh] funcnts -sr snr.ev "ann 512 512 0 9 n=3"
  # source
  #   data file:        /proj/rd/data/snr.ev

There are four tables in this output. To extract the last one, you can execute:

  [sh] funcnts -s snr.ev "ann 512 512 0 9 n=3" | funtbl -n 4
  1 147.000 25 147.000 25
  2 478.000 84 625.000 109
  3 817.000 140 1442.000 249

Note that the output has been re-formatted so that only a single space separates each column, with no extraneous header or comment information.

To extract only columns 1,2, and 4 from the last example (but with a header prepended and tabs between columns), you can execute:

  [sh] funcnts -s snr.ev "ann 512 512 0 9 n=3" | funtbl -c "1 2 4" -h -n 4 -s "\t"
  #reg    counts  sumcnts
  1       147.000 147.000
  2       478.000 625.000
  3       817.000 1442.000

Of course, if the output has previously been saved in a file named foo.out, the same result can be obtained by executing:

  [sh] funtbl -c "1 2 4" -h -n 4 -s "\t" foo.out
  #reg    counts  sumcnts
  1       147.000 147.000
  2       478.000 625.000
  3       817.000 1442.000
