=head1 NAME
B<funtbl - extract a table from Funtools ASCII output>
=head1 SYNOPSIS
funtable [-c cols] [-h] [-n table] [-p prog] [-s sep] <iname>
=head1 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 B<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"

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
