# gpiv\_rot180(1)

Simple data manipulation tool for PIV data.

## NAME

gpiv\_rot180 - Simple data manipulation tool for PIV data.

## SYNOPSIS

**gpiv\_rot180**  \[**-h** \| **--help**\]  \[**-p** \| **--print**\]  \[**-p** \| **--version**\]  \[*filename*\]  \< *stdin* \> *stdout*

## DESCRIPTION

**gpiv\_rot180** *rotates the data over 180 degrees.  As rotating over 180* *degrees is identic to flipping over x as well as over y-direction,* **flipx** and **flipy** may be used instead of **gpiv\_rot180**.

The parameters read from the configuration resources (containing the key **POST**) may be overruled by the command 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 may be used as parameters of **gpiv\_rot180** for future use by re-directing stdout to *gpiv\_rot180.par*.

- **-v** \| **--version**

  Print version information on standard output, then exits successfully.

- *filename*

  Input PIV file. Overrides stdin and stdout. Output will be written to *filename***.ma.piv**. The parameters will be written or appended to *filename***.par**.
