Thanks for your help Smilie

I am trying to apply this idea to "degrade" the output of a model resolution.

For the sample:

$ vi model.dat

Code:

3002.000 1.2874e+32
3002.300 1.2898e+32
3002.600 1.2966e+32
3002.900 1.3000e+32
3003.200 1.2997e+32
3003.500 1.2961e+32
3003.800 1.2926e+32
3004.100 1.2909e+32
3004.400 1.2904e+32
3004.700 1.2923e+32
3005.000 1.2970e+32
3005.300 1.3027e+32
3005.600 1.3043e+32
3005.900 1.3028e+32
3006.200 1.2977e+32
3006.500 1.2894e+32
3006.800 1.2802e+32
3007.100 1.2738e+32
3007.400 1.2717e+32
3007.700 1.2728e+32
3008.000 1.2778e+32

I want to "somehow" degrade the resolution of the first column from 0.3 to 3 for the corresponding numbers in the second column something like this:

Code:

3002.000 ???
3005.000 ???
3008.000 ???

Where the "???" are the numbers I am trying to obtain using the awk script that you suggested but I am not able to get the results Smilie

. Any suggestions?

NAME

       odt2txt - a simple converter from OpenDocument Text to plain text

SYNOPSIS

       odt2txt [OPTIONS] FILENAME

DESCRIPTION

       odt2txt	is  a  command-line tool which extracts the text out of OpenDocument Texts, as produced by OpenOffice.org, KOffice, StarOffice and
       others.

       odt2txt can also extract text from some file formats similar to OpenDocument Text, such as OpenOffice.org XML (*.sxw), which  was  used	by
       OpenOffice.org  version	1.x and older StarOffice versions.  To a lesser extend, odt2txt may be useful to extract content from OpenDocument
       spreadsheets (*.ods) and OpenDocument presentations (*.odp).

       The FILENAME argument is mandatory.

OPTIONS

       --width=WIDTH
	      Wrap text lines after WIDTH characters. The default value is 65, which means that any words which would extend beyond column 65  are
	      moved to a new line.

	      If WIDTH is set to -1 then no lines will be broken

       --output=FILE
	      Write output to FILE and not to standard output.

       --subst=SUBST
	      Select which non-ascii characters shall be replaced by ascii look-a-likes. Valid values for SUBST are all, some and none.

	      --subst=all Substitute all characters for which substitutions are known

	      --subst=some Substitute all characters which the output charset does not contain This is the default

	      --subst=none Substitute no characters

       --encoding=X
	      Do  not  try to autodetect the terminal encoding, but convert the document to encoding X unconditionally To find out, which terminal
	      encoding will be used in automatic mode, use --encoding=show

       --raw  Print raw XML

       --version
	      Show version and copyright information
