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"

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
