gpiv_sstrain - Calculates the shear strain from PIV data.
SYNOPSIS
gpiv_sstrain [-d N] [-h | --help] [--no_g ] [-p | --print] [-g | --g] [-v | --version] [filename] < stdin > stdout
DESCRIPTION
gpiv_sstrain calculates the shear strain from PIV data. You can choose from several differential schemes: central differentiation, least
squares and Richardson extrapolation. The output can be generated as ASCII data containing four columns or as GNUPlot Data format that
allows one to view/print the data as contour plots.
The configuration parameters (containing the POST key) may be overruled by the command line options, as explained below.
Options-d N Differential type to be used: central difference (N=0), least squares (N=1), Richardson interpolation (N=2), circulation method
(N=3)
-h | --help
On-line help
-p | --print
Print parameters, command line options and eventually used input and output filenames to stdout. The output is identic of file-
name.par, in case filename is used.
-g Show contour plot of the output with gnuplot.
--no_g Suppresses to show contour plot of the output with gnuplot.
-v | --version
Print version information on standard output, then exit successfully.
filename Input PIV data file. Overrides stdin and stdout. The
output will be written to filename.sstr. Parameters are stored in filename.par and may be used for future use by including them in
./gpivrc.

Command output is given to the console. As in the following case -
wc -l filename
produces following output
nn filename
From this, I am only interested with nn(rowcount). Cant we simply extract it thr console?
I also tried with null device, I know as - /dev/null

I am trying to get some data from a file and print it on the same line.
I have a script that gets the date/time and calculates a DB query call time and sends to a file. I need to take this file and send it in a xcel like format with multiple data columns.

Hi Experts,
I have to display rdiff in a readable format.
The rdiff output is as under:
Index: ivapp_conf/etc/PrdWest/process.par

I'm running a simulation (programmed in C) which makes calls to gnuplot periodically to plot data I have stored.
First I open a pipe to gnuplot and set it to multiplot:
FILE * pipe = popen("gnuplot", "w");
fprintf(pipe, "set multiplot\n");
fflush(pipe);
(this pipe stays open until the... (0 Replies)
When I plot a set of data in gnuplot from a file like:
1 5
2 3
4 6
5 1
using
plot "file.txt" w boxes
I would expect that at the x value of 3 it will go to a value of 0 for y... but it doesn't. Is there a way to fix that, or do I actually have to type by hand an... (1 Reply)
My input data has occasional holes in it, spots where a sensor couldn't be read. These are ERR in the data file instead of a floating point number. What should I change them to, for gnuplot to ignore these values instead of whining about them? (1 Reply)
hi,
please can I ask you for some help? I have data from 3D situation, x y z value
I'd like to use gnuplot to generate maps of the value in the planes z=0 to z=1 for example, my file looks
like
-0,012 0,0060 0,0 0,13972813076023477

Hello,
I have a file with two columns (I uploaded it because it is some 500K):
File-Upload.net - data.dat
If you plot the data with, say, gnuplot,
plot 'data.dat' u 1:2 w l
you will see that there are jumps. This is actually an orbit and a maximum corresponds to an apocenter and a... (2 Replies)
Hi,
I have been struggling for quite past few days to make or generate graphs using a loop in the GNUPLOT.
I am trying to generate a contour plot using "splot" command in gnuplot. I am able to do for a single file successfully. But i am unable to make it work for more number of files using a... (2 Replies)
I am trying to fit a plot in gnuplot using logscale. I have 50000 data points. At first I fit plot in this way.
f(x) = b + m*x
fit f(x) "xyMSD-all-mal-cel-iso-bcm-thermo2.dat" using 1:2 via m,b
I got slope value. Then I tried to get slope value at different range as below.
