GPIV_PIV2HDF(1) 					      General Commands Manual						   GPIV_PIV2HDF(1)

NAME
gpiv_piv2hdf - Converts PIV-data HDF5 format. SYNOPSIS
gpiv_piv2hdf [-e] [-h | --help] [-p | --print] [-v | --version] [-V | --verbose] filename DESCRIPTION
gpiv_piv2hdf converts ASCII-formattd PIV-data (filename.piv), derived data, like vorticities (filename.vor), strain (filename.sstr, file- name.nstr) and, eventually, raw data images (filename.r), to a HDF5 formatted file filename.hdf. The parameters that have been used for the analysis and post processing are included in filename.hdf. This program does not use the parameter resources from libgpiv. The parameters may be defined by the command line options as explained below. Options -e Exclude PIV data and data from post-processes. -h | --help On-line help. -i Includes image data. -p | --print Prints parameters, command line options and input and output filenames to stdout. The output may be used as parameters of fasty for future use by re-directing stdout to fasty.par. -v | --version Print version information on standard output, then exits successfully. -V | --verbose Program behaves more verbose by printing messages to stdout. filename Input PIV data filename, including .piv extension.
