GPIV_T-AVG-IMG(1) General Commands Manual GPIV_T-AVG-IMG(1)NAME
gpiv_t-avg-img - Calculates time-averaged intensities from a series of images at each pixel.
SYNOPSIS
gpiv_t-avg-img [-c int] [-fb string] [-ff int] [-fl int] [-fx] [-help] [-p | --print] [-r int] [-s] [-v] < stdin > stdout
DESCRIPTION
gpiv_t-avg-img calculates time-averaged intensities from a series of images for each pixel. This program uses the GENPAR parameters.
Options-c NCOLS
Number of columns.
-fb FILE
File base-name (without .number.r extension) instead of stdin and stdout.
-ff N Number of first image file.
-fl N Number of last image file.
-fx Prefix numbering to file base name.
-help | --help
On-line help.
-p | --print
Prints parameters, command line options and input and output filenames to stdout.
-r NROWS
Number of rows.
-s Subtract mean from input data. -v | --version Prints version information to standard output, then exits successfully.

gpiv_scale - Scaling of PIV data.
SYNOPSIS
gpiv_scale [-h | --help] [-p | --print] [-s M |-S M] [-t dT |-T dT] [-v | --version] [-zp x0 y0] [-zv x0 y0] [filename] < stdin > stdout
DESCRIPTION
gpiv_scale applies the image magnification and the time between successive recordings to the PIV estimators. This results that particle
displacements [px] are modified to velocities [m/s] and their positions from [px] to [m]. A physical reference for the positions of the PIV
data can be applied by means of the image zero-offset option.
If filename is used, the parameters and options to be used for gpiv_scale are subsequently read from the image header (filename.h in case
of raw binary images) or from the configuration resources (containing the IMG and POST keys). The parameters may be overruled by the com-
mand line options, as explained below.
Options-h | --help
On-line help.
-p | --print
Prints parameters, command line options and input and output filenames to stdout. The output is identic of filename.par, in case -f
is used.
-s M spatial scaling with magnification factor M [m/px]
-S M Inverse spatial scaling with magnification factor M [m/px]; returns scaled data to their original magnitudes.
-v | --version
Prints version information on standard output, then exits successfully.
-t dT Translates particle displacements into velocities by devising them with the time between subsequent recordings dT [s].
-T dT Inverse time scaling. Returns velocities into displacements [px]
[-z x0 y0]
Relates the positions of the observations of velocities/displacements to a physical location in the experiment by image zero offset-
ting. x0 y0 denote the physical position of pixel (0,0) in the image.
filename
Input PIV file. Overrides stdin and stdout. The output will be written to filename.sc.piv. Parameters are stored in filename.par and
may be used for future use by including them in ./gpivrc.

BUGS
The program has been tested for PIV data. So far, no bugs have been found.

Hi,
I have a windows emulator that I am wanting to try out, but my Windows 3.1 files are split up over 6 .DSK images, and I need to convert them to an .IMG that I can actually mount on my system (so that the emulator can see it).
Is there a way to do this?
thanks.

I've been trying to create an IMG file for the past week with no success. I've tried using:

mke2fs myimage.img
mkdir /media/mount_point
mount -o loop myimage.img /media/mount_point

I need to read a file, the file has a table in it. From the table I need to choose all the rows for which AVG 2 value is greater than 0.050 and write them on to a separate file. Please help me with the TCL script for this.

Hi,
I've got as far as this: awk '{sum+=$1}(NR%3==1){avg=sum/3; print avg}' input.txt
Input it:
0.1

0.3

So, the I get the results:

Hi,
I have a file with contents
So what I have to do is
In short, break the file after every 6 lines and then truncate new line to tab for these 6 lines.
I am not able to execute the for loop in awk properly.
The idea is something like this:
less file| awk '{for .... {if ((nr>=1)... (7 Replies)
